Weakly interacting quasiparticles play a central role in the low-energy description of many
phases of quantum matter. At higher energies, however, quasiparticles cease to be well …

Scar states are special many-body eigenstates that weakly violate the eigenstate
thermalization hypothesis (ETH). Using the explicit formalism of the Lanczos algorithm …

The high level of control and precision achievable in current synthetic quantum matter
setups has enabled first attempts at quantum-simulating various intriguing phenomena in …

We study quantum many-body scars (QMBS) in the language of commutant algebras, which
are defined as symmetry algebras of families of local Hamiltonians. This framework explains …

The concept of “deep thermalization” has recently been introduced to characterize moments
of an ensemble of pure states, resulting from projective measurements on a subsystem …

Quantum many-body scars (QMBS) are exceptional energy eigenstates of quantum many-
body systems associated with violations of thermalization for special nonequilibrium initial …

Quantum dynamics in certain kinetically-constrained systems can display a strong sensitivity
to the initial condition, wherein some initial states give rise to persistent quantum revivals—a …

Highly excited eigenstates of quantum many-body systems are typically featureless thermal
states. Some systems, however, possess a small number of special, low-entanglement …

We construct a family of three-body spin-1 2 Hamiltonians with a superextensive set of
infinitely long-lived multimagnon states. A magnon in each such state carries either …

The Rydberg blockade induces strongly correlated many-body effects in Rydberg atom
arrays, including rich ground-state phases and many-body scar states in the excitation …
