Fracton phases of matter
Fractons are a new type of quasiparticle which are immobile in isolation, but can often move
by forming bound states. Fractons are found in a variety of physical settings, such as spin …

Observing non-ergodicity due to kinetic constraints in tilted Fermi-Hubbard chains
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 …

Localization from Hilbert space shattering: From theory to physical realizations
We show how a finite number of conservation laws can globally “shatter” Hilbert space into
exponentially many dynamically disconnected subsectors, leading to an unexpected …

Hilbert-space fragmentation from strict confinement
We study one-dimensional spin-1/2 models in which strict confinement of Ising domain walls
leads to the fragmentation of Hilbert space into exponentially many disconnected …

Confinement and lack of thermalization after quenches in the bosonic Schwinger model
We excite the vacuum of a relativistic theory of bosons coupled to a U (1) gauge field in 1+ 1
dimensions (bosonic Schwinger model) out of equilibrium by creating a spatially separated …

Confined Phases of One-Dimensional Spinless Fermions Coupled to Gauge Theory
We investigate a quantum many-body lattice system of one-dimensional spinless fermions
interacting with a dynamical Z 2 gauge field. The gauge field mediates long-range attraction …
