Quantum many-body scars: A quasiparticle perspective
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 …

Quantum many-body scars and Hilbert space fragmentation: a review of exact results
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 …

Subsystem non-invertible symmetry operators and defects
We explore non-invertible symmetries in two-dimensional lattice models with subsystem
$\mathbb Z_2 $ symmetry. We introduce a subsystem $\mathbb Z_2 $-gauging procedure …

Enhanced many-body quantum scars from the non-Hermitian Fock skin effect
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 …

Fractonic Luttinger liquids and supersolids in a constrained Bose-Hubbard model
Quantum many-body systems with fracton constraints are widely conjectured to exhibit
