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 …

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 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 class of Hamiltonians H for which a sector of the Hilbert space invariant under
a Lie group G, which is not a symmetry of H, possesses the essential properties of many …

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 …

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 …

We show that a quantum scar state, an atypical eigenstate breaking eigenstate
thermalization hypothesis embedded in a many-body energy spectrum, can be constructed …
