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*](https://www.cambridge.org/gb/universitypress/subjects/physics/condensed-matter-physics-nanoscience-and-mesoscopic-physics/quantum-phases-matter?format=HB). The first complete emergent gauge theory of quantum antiferromagnets with time-reversal symmetry was introduced. The importance of Berry phases (now often characterized as `anomalies') was pointed out, and these Berry phases 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 *Z2* spin liquid, was presented. This was described by an emergent *Z2* gauge 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 allowed because the 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. This theory led to the proposal of hydrodynamic electron flow in graphene and related two-dimensional materials. 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. **Books** - [*Quantum Phase Transitions*](https://www.cambridge.org/gb/universitypress/subjects/physics/condensed-matter-physics-nanoscience-and-mesoscopic-physics/quantum-phase-transitions-2nd-edition?format=HB), Cambridge University Press, Cambridge (1999); paperback in 2001; expanded second edition in 2011. - [*Holographic Quantum Matter*](https://mitpress.mit.edu/9780262038430/), with Andrew Lucas and Sean Hartnoll, MIT Press, 2018 - [*Quantum Phases of Matter*](https://www.cambridge.org/gb/universitypress/subjects/physics/condensed-matter-physics-nanoscience-and-mesoscopic-physics/quantum-phases-matter?format=HB), Cambridge University Press, Cambridge (2023).
