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 thermalization of isolated quantum many-body systems is deeply related to fundamental
questions of quantum information theory. While integrable or many-body localized systems …

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 …

The η-pairing states are a set of exactly known eigenstates of the Hubbard model on
hypercubic lattices, first discovered by Yang [CN Yang, Phys. Rev. Lett. 63, 2144 (1989) …

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

Exact solutions for quantum many-body systems are rare but provide valuable insights for
the description of universal phenomena such as the non-equilibrium dynamics of strongly …

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 geometrical frustration has led to rich insights into condensed matter physics,
especially as a mechanism to produce exotic low-energy states of matter. Here we show that …
