text: 'Thermalizing quantum systems are conventionallydescribed by statistical mechanics
at equilib-rium. However, not all systems fall into this category, with many-body
localization providinga generic mechanism for thermalization to fail in strongly
disordered systems. Many-bodylocalized (MBL) systems remain perfect insulators
at nonzero temperature, which do notthermalize and therefore cannot be describedusing
statistical mechanics. This Colloquiumreviews recent theoretical and experimental
advances in studies of MBL systems, focusing onthe new perspective provided by
entanglement and nonequilibrium experimental probes suchas quantum quenches. Theoretically,
MBL systems exhibit a new kind of robust integrability: anextensive set of quasilocal
integrals of motion emerges, which provides an intuitive explanationof the breakdown
of thermalization. A description based on quasilocal integrals of motion isused
to predict dynamical properties of MBL systems, such as the spreading of quantumentanglement,
the behavior of local observables, and the response to external dissipativeprocesses.
Furthermore, MBL systems can exhibit eigenstate transitions and quantum ordersforbidden
in thermodynamic equilibrium. An outline isgiven of the current theoretical under-standing
of the quantum-to-classical transitionbetween many-body localized and ergodic
phasesand anomalous transport in the vicinity of that transition. Experimentally,
synthetic quantumsystems, which are well isolated from an external thermal reservoir,
provide natural platforms forrealizing the MBL phase. Recent experiments with
ultracold atoms, trapped ions, superconductingqubits, and quantum materials, in
which different signatures of many-body localization have beenobserved, are reviewed.
This Colloquium concludes by listing outstanding challenges andpromising future
research directions.'
