Subir Sachdev - Curriculum Vitae 4 Introduction to Research Sachdev’s research describes the consequences of quantum entanglement on the macroscopic properties of natural systems. He has made extensive contributions to the description of the diverse varieties of states of quantum matter, and of their behavior near quantum phase transitions. Many of these contributions have been linked to experiments, especially to the rich phase diagrams of the copper-oxide high temperature superconductors. Sachdev’s research has also exposed remarkable connections between the nature of multi-particle quantum entanglement in certain laboratory materials, and the quantum entanglement in astrophysical black holes, and these connections have led to new insights on the entropy and radiation of black holes. Research Highlights Sachdev has studied the nature of quantum entanglement in two-dimensional antiferromagnets, introducing several key ideas in a series of papers in 1989-1992, and reviewed in his book Quantum Phases of Matter. The first complete emergent gauge theory of quantum antiferromagnets with time-reversal symmetry was introduced. The importance of the analog of ’t Hooft/Lieb-Schultz-Mattis anomalies was pointed out, and these anomalies have played a central role in the theory of gapped and gapless quantum spin liquids, including those realized by ‘deconfined critiality’. By considering Higgs transitions of the emergent U(1) gauge field, the first theory of a gapped fractionalized spin liquid phase with time-reversal symmetry, the Z2spin liquid, was presented. This was described by an emergent Z2gauge theory, with the same structure of excitations that appeared later in Kitaev’s solvable toric code model. This framework also led to the discovery in 2002 of quantum spin liquid states which have metallic Fermi surfaces in ‘fractionalized Fermi liquids (FL*)’. The FL* Fermi surface does not enclose the Luttinger volume, and this is allowed because the ’t Hooft/LSM anomaly of a quantum spin liquid can offset the Luttinger count. Sachdev has developed the theory of quantum criticality, elucidating its implications for experimental observations on materials at non-zero temperature. In this context, he proposed a solvable model of complex quantum entanglement in a metal which does not have any particle-like excitations in 1993: an extension of this is now called the Sachdev-Ye-Kitaev (SYK) model. These works have led to a theory of quantum phase transitions in metals in the presence of impurity-induced disorder, and a universal theory of strange metals. Sachdev’s theories apply to a wide variety of correlated electron materials, including the copper-oxide materials exhibiting high temperature superconductivity. Many puzzling features of the ‘pseudogap’ phase of these materials are addressed by his works on the interplay between antiferromagnetism and superconductivity, using the theory of critical quantum spin liquids without quasiparticles. A connection between the structure of quantum entanglement in the SYK model and in black holes was first proposed by Sachdev in 2010, and these connections have led to extensive developments in the quantum theory of black holes. Sachdev has written 3 books describing this research: Quantum Phase Transitions (1999), Holographic Quantum Matter (with Andrew Lucas and Sean Hartnoll, 2018), and Quantum Phases of Matter (2023). See also the description his work on the Wikipedia page: Subir Sachdev. Quantum criticality, superconductors, and black holes Extreme examples of complex quantum entanglement arise in metallic states of matter without quasiparticle excitations, often called strange metals. Such metals are invariably present in higher temperature superconductors, above the highest transition temperatures for superconductivity. The strange metallicity and superconductivity are manifestations of an underlying quantum critical state of matter without quasiparticle excitations. Remarkably, there is an intimate connection between the quantum physics of strange metals in modern materials (which can be studied in tabletop experiments), and quantum entanglement near black holes of astrophysics. Subir Sachdev - Curriculum Vitae 5 This connection is most clearly seen by thinking more carefully about the defining characteristic of a strange metal: the absence of quasiparticles. In practice, given a state of quantum matter, it is difficult to completely rule out the existence of quasiparticles: while one can confirm that certain perturbations do not create single quasiparticle excitations, it is almost impossible to rule out a non-local operator which could create an exotic quasiparticle in which the underlying electrons are non-locally entangled. Using theories of quantum phase transitions, Sachdev argued (Quantum Phase Transitions,Physical Review B 56, 8714 (1997)) instead that it is better to examine how rapidly the system loses quantum phase coherence, or reaches local thermal equilibrium in response to general external perturbations. If quasiparticles existed, dephasing would take a long time during which the excited quasiparticles collide with each other. In contrast, states without quasiparticles reach local thermal equilibrium in the fastest possible time, bounded below by a value of order (Planck constant)/((Boltzmann constant)×(absolute temperature)). Sachdev proposed (Physical Review Letters 70, 3339 (1993),Physical Review X 5, 041025 (2015)) a solvable model of a strange metal (a variant of which is now called the Sachdev-Ye-Kitaev (SYK) model), which was shown to saturate such a bound on the time to reach quantum chaos (Journal of High Energy Physics 2016, 106 (2016)). We can now make the connection to the quantum theory of black holes: quite generally, black holes also thermalize and reach quantum chaos in a time of order (Planck constant)/((Boltzmann constant) x (absolute temperature)), where the absolute temperature is the black hole’s Hawking temperature. And this similarity to quantum matter without quasiparticles is not a co-incidence: Sachdev argued (Physical Review Letters 105, 151602 (2010)) that the SYK model maps holographically to the low energy physics of charged black holes in 4 spacetime dimension. Also key to this connection were the facts that in the limit of zero temperature, charged black holes have a non-zero entropy proportional to the horizon area, and the SYK model has a non-zero entropy density (Physical Review B 63, 134406 (2001)). Indeed, the SYK model was the first model to exhibit a non-vanishing zero temperature entropy density without an exponentially large ground state degeneracy, and so the holographic mapping implied that charged black holes share this feature. These and other related works on quantum criticality by Sachdev and collaborators have led to insights on the properties of electronic quantum matter, and on the nature of Hawking radiation from black holes. Solvable models related to gravitational duals and the SYK model have led to the discovery of more realistic models of quantum phase transitions in the high temperature superconductors and other compounds. Advances in the theory of quantum transitions in metals in the presence of impurities have led to a universal theory of strange metals which applies across a wide range of correlated electron compounds. Such predictions (Physical Review B 78, 115419 (2008),Science 381, 790 (2023),Physical Review Letters 133, 186502 (2024)) have been connected to experiments on graphene (Science 351, 1055 (2016),Science 351, 1058 (2016)) and the cuprate superconductors (Nature Communications 14, 3033 (2023)). The SYK model plays a key role in the computation of the density of low energy quantum states of non-supersymmetric charged black holes in 4 spacetime dimensions (arXiv:2209.13608,arXiv:2304.13744), and provides the underlying Hamiltonian system upon which advances on the Page curve of entanglement entropy of evaporating black holes have been tested (see arXiv:2201.03096 for a review). Sachdev has also developed the theory of critical quantum spin liquids which feature fractionalization and emergent gauge fields, along with absence of quasiparticles. Such spin liquids with gapless excitations play an important role in the theory of the cuprate superconductors. Resonating valence bonds and Z2quantum spin liquids P.W. Anderson proposed in 1973 that Mott insulators realize antiferromagnets which could form resonating valence bond (RVB) states i.e. quantum spin liquid states with an energy gap to spin excitations without breaking time-reversal symmetry. (Anderson also proposed in 1987 that RVB spin correlations are important for high temperature superconductivity in the cuprates; but as noted above, Sachdev has instead argued that the relevant states are critical quantum spin liquids without quasiparticles.) It was conjectured that such RVB states have excitations with fractional quantum numbers, such as a fractional spin 1/2. The existence Subir Sachdev - Curriculum Vitae 6 of such RVB ground states, and of the deconfinement of fractionalized excitations was first established by Read and Sachdev (Physical Review Letters 66, 1773 (1991)) and Wen (Physical Review B 44, 2664 (1991)) by the connection to a Z2gauge theory. Sachdev was also the first to show that the RVB state is an ‘odd’ Z2gauge theory, (Physical Review B 44, 686 (1991),Journal of the Physical Society of Japan 69, Suppl. B, 1 (2000),Reports on Progress in Physics 82, 014001 (2019)). An odd Z2spin liquid has a background Z2electric charge on each lattice site (equivalently, translations in the xand ydirections anti-commute with each other in the super-selection sector of states associated with a Z2gauge flux (also known as the m sector)); this is another example of a ’t Hooft/LSM anomaly. Sachdev showed that antiferromagnets with half-integer spin form odd Z2spin liquids, and those with integer spin form even Z2spin liquids. Using this theory, various universal properties of the RVB state were understood, including constraints on the symmetry transformations of the anyon excitations. Sachdev also obtained many results on the confinement transitions of the RVB state, including restrictions on proximate quantum phases and the nature of quantum phase transitions to them. The topological order (i.e. ground state degeneracies on 2-manifolds) and anyons of Z2quantum spin liquids are identical to those which appeared later in the solvable toric code model, which plays a key role in quantum error correction in qubit devices. Z2spin liquids are ground states of spin models on the kagome lattice, and this has been connected to experiments on correlated electron materials and arrays of trapped Rydberg atoms. 5 selected papers with commentaries 1. Gapless spin-fluid ground state in a random quantum Heisenberg magnet, S. Sachdev and J. Ye, Physical Review Letters 70, 3339 (1993). This was the first soluble model of a quantum many-body system with the following properties: •No quasiparticle excitations. •Universal dissipative ‘Planckian’ dynamics on the time scale ℏ/(kBT). •Extensive zero temperature entropy without an exponentially large ground state degeneracy. This model has since had an extensive influence on the theory of quantum phase transitions in metals, and on the quantum theory of charged black holes. 2. Non-zero temperature transport near quantum critical points, K. Damle and S. Sachdev, Physical Review B 56, 8714 (1997). This papers introduced ideas on what is now often called “Planckian dynamics” in the transport of quantum critical systems. The original motivations and applications were to antiferromagnetic, superfluid-insulator and quantum Hall transitions, but there have also been diverse applications across other quantum critical systems: •L. Fritz, J. Schmalian, M. M¨uller and S. Sachdev, Physical Review B 78, 085416 (2008) interpreted the transport properties of pure graphene along quantum-critical lines, to the surprise of many in the field. This led to predictions for microwave conductivity which were experimentally observed in Gallagher et al. Science 364, 158 (2019). M. M¨uller and S. Sachdev, Physical Review B 78, 115419 (2008) were the first to propose that graphene should display hydrodynamic transport near charge neutrality. This is now a flourishing subject with many experimental studies of hydrodynamics in two-dimensional materials, especially graphene e.g. Mark Ku et al.,Nature 583, 537 (2020). •The Damle-Sachdev paper motivated holographic models of transport in quantum-critical matter by C. P. Herzog, P. Kovtun. S. Sachdev, and D. T. Son, Physical Review D 75, 085020 (2007) and S. A. Hartnoll, P. K. Kovtun, M. M¨uller, and S. Sachdev, Physical Review B 76, 144502 (2007). Subir Sachdev - Curriculum Vitae 7 This led to extensive work on holographic theories of strongly interacting matter, as reviewed in the book Holographic Quantum Matter by S. Hartnoll, A. Lucas, and S. Sachdev. It also led to the realization that transport in clean quantum critical systems is in the strong drag limit. 3. Holographic Metals and the Fractionalized Fermi Liquid, S. Sachdev, Physical Review Letters 105, 151602 (2010) There has been a direct and extensive impact from the theory of quantum criticality in condensed matter physics to the quantum theory of black holes via the 1993 paper by Sachdev and Ye and this paper by Sachdev in 2010. The 2010 paper was the first to point out that ‘certain mean-field gapless spin liquids’ are quantum matter states without quasiparticle excitations realizing the low energy quantum physics of charged black holes. With ‘mean-field gapless spin liquids’ Sachdev was referring to what can now be called the SYK critical state. Based on results in A. Georges, O. Parcollet, and S. Sachdev, Physical Review B 63, 134406 (2001), Sachdev argued in the 2010 paper for a correspondence between the SYK model and charged black holes at the semiclassical level. The connection was based on the common Planckian dynamics and extensive zero temperature entropy, and implied that the BekensteinHawking black hole entropy is not realized by an exponentially large ground state degeneracy. In 2015, Kitaev (Talks at KITP, University of California, Santa Barbara) showed that the correspondence held at the fully quantum level. This connection has undergone rapid development in recent years, and has led to an understanding of the generic universal structure of the low-energy density of states of non-supersymmetric charged black holes in D≥4 spacetime dimensions (L.V. Iliesiu, S. Murthy and G.J. Turiaci, arXiv:2209.13608, S. Sachdev arXiv:2304.13744). The SYK model has also been a key testing ground for recent advances in understanding Hawking radiation—see the review, R. Buosso et al.,arXiv:2201.03096. 4. Universal theory of strange metals from spatially random interactions, A. A. Patel, Haoyu Guo, I. Esterlis, and S. Sachdev, Science 381, 790 (2023). This paper develops a theory of quantum phase transition of two-dimensional metallic systems in the presence of random impurities. Surprisingly, the various clean Hertz-Millis classes, and also the topological transitions involving without broken symmetries all fall into essentially the same universality class. There is a wide intermediate temperature regime over which the solution of two-dimensional generalization of the Sachdev-Ye-Kitaev model applies. These results explain strange metal data in the cuprates and other compounds e.g. the d.c. and optical conductivity in Michon et al. Nature Communications 14, 3033 (2023) as described in Strange metal and superconductor in the two-dimensional Yukawa-Sachdev-Ye-Kitaev model , Chenyuan Li, D. Valentinis, A. A. Patel, Haoyu Guo, J. Schmalian, S. Sachdev, and I. Esterlis, Physical Review Letters 133, 186502 (2024). 5. Valence bond and spin-Peierls ground states of low dimensional quantum antiferromagnets, N. Read and S. Sachdev, Physical Review Letters 62, 1694 (1989). This paper was the first complete emergent gauge theory of a two-dimensional quantum spin liquid, introducing numerous key ideas which have since played important roles in the development of the theory of entangled states of quantum matter. •The importance of the analog of ’t Hooft /Lieb-Schultz-Mattis anomalies (realized here as monopole Berry phases) was pointed out. Such anomalies have since played a central role in the theory of gapped and gapless quantum spin liquids, and of quantum phase transitions out of them, including those realized by ‘deconfined critiality’ (T. Senthil, A. Vishwanath, L. Balents, S. Sachdev, and M. P. A. Fisher, Science 303, 1490 (2004)). •By considering Higgs transitions of the emergent gauge field, N. Read and S. Sachdev, Physical Review Letters 66, 1773 (1991) introduced the first example of fractionalized state of matter with time-reversal symmetry—the Z2spin liquid. Subir Sachdev - Curriculum Vitae 8 •The importance of ’t Hooft/LSM anomalies in the Z2spin liquid was pointed out by R. Jalabert and S. Sachdev, Physical Review B 44, 686 (1991) and S. Sachdev and M. Vojta, Journal of the Physical Society of Japan 69 Supplement B, 1 (2000), and this showed that Anderson’s resonating valence bond state was an ‘odd’ Z2spin liquid. •This framework also led to the discovery of quantum spin liquid states which have metallic Fermi surfaces in ‘fractionalized Fermi liquids (FL*)’, T. Senthil, S. Sachdev, and M. Vojta, Physical Review Letters 90, 216403 (2003). The FL* Fermi surface does not enclose the Luttinger volume, and this allowed because the ’t Hooft/LSM anomaly of a quantum spin liquid can offset the Luttinger count. Such FL* states provide a description of intermetallic ‘heavy fermion’ compounds (e.g. CeCoIn5in Maksimovic et al.,Science 375, 76 (2021)) and the ‘pseudogap’ phase of the cuprate high temperature superconductors.
