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 …

We study the phenomenon of Hilbert space fragmentation in isolated Hamiltonian and
Floquet quantum systems using the language of commutant algebras, the algebra of all …

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

Explaining quantum many-body dynamics is a long-held goal of physics. A rigorous operator
algebraic theory of dynamics in locally interacting systems in any dimension is provided …

In contrast with extended Bloch waves, a single particle can become spatially localized due
to the so-called skin effect originating from non-Hermitian pum**. Here we show that in …

As a paradigm of weak ergodicity breaking in disorder-free nonintegrable models, quantum
many-body scars (QMBS) can offer deep insights into the thermalization dynamics of gauge …

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

Quantum many-body scars are an intriguing dynamical regime in which quantum systems
exhibit coherent dynamics and long-range correlations when prepared in certain initial …
