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 …

The discovery of quantum many-body scars (QMBS) both in Rydberg atom simulators and in
the Affleck–Kennedy–Lieb–Tasaki spin-1 chain model, have shown that a weak violation of …

Thermalization is the inevitable fate of many complex quantum systems, whose dynamics
allow them to fully explore the vast configuration space regardless of the initial state—the …

The preparation of long-range entangled states using unitary circuits is limited by Lieb-
Robinson bounds, but circuits with projective measurements and feedback (“adaptive …

We show that the combination of charge and dipole conservation—characteristic of fracton
systems—leads to an extensive fragmentation of the Hilbert space, which, in turn, can lead …

Quantum many-body scarring (QMBS) is a recently discovered form of weak ergodicity
breaking in strongly interacting quantum systems, which presents opportunities for mitigating …

We revisit the η-pairing states in Hubbard models and explore their connections to quantum
many-body scars to discover a universal scars mechanism. η-pairing occurs due to an …

We construct a set of exact, highly excited eigenstates for a nonintegrable spin-1/2 model in
one dimension that is relevant to experiments on Rydberg atoms in the antiblockade regime …

We consider the spectrum of a U (1) quantum link model where gauge fields are realized as
S= 1/2 spins and demonstrate a new mechanism for generating quantum many-body scars …

We present a general symmetry-based framework for obtaining many-body Hamiltonians
with scarred eigenstates that do not obey the eigenstate thermalization hypothesis. Our …
