Fracton phases of matter

M Pretko, X Chen, Y You - International Journal of Modern Physics …, 2020 - World Scientific
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

S Scherg, T Kohlert, P Sala, F Pollmann… - Nature …, 2021 - nature.com
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

V Khemani, M Hermele, R Nandkishore - Physical Review B, 2020 - APS
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

ZC Yang, F Liu, AV Gorshkov, T Iadecola - Physical review letters, 2020 - APS
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 …

Simple mitigation of global depolarizing errors in quantum simulations

J Vovrosh, KE Khosla, S Greenaway, C Self, MS Kim… - Physical Review E, 2021 - APS
To get the best possible results from current quantum devices error mitigation is essential. In
this work we present a simple but effective error mitigation technique based on the …

False vacuum decay in quantum spin chains

G Lagnese, FM Surace, M Kormos, P Calabrese - Physical Review B, 2021 - APS
The false vacuum decay has been a central theme in physics for half a century with
applications to cosmology and to the theory of fundamental interactions. This fascinating …

Confinement and lack of thermalization after quenches in the bosonic Schwinger model

T Chanda, J Zakrzewski, M Lewenstein… - Physical Review Letters, 2020 - APS
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

U Borla, R Verresen, F Grusdt, S Moroz - Physical Review Letters, 2020 - APS
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 …

Scattering of mesons in quantum simulators

FM Surace, A Lerose - New Journal of Physics, 2021 - iopscience.iop.org
Simulating real-time evolution in theories of fundamental interactions represents one of the
central challenges in contemporary theoretical physics. Cold-atom platforms stand as …

Entanglement oscillations near a quantum critical point

OA Castro-Alvaredo, M Lencsés, IM Szécsényi, J Viti - Physical Review Letters, 2020 - APS
We study the dynamics of entanglement in the scaling limit of the Ising spin chain in the
presence of both a longitudinal and a transverse field. We present analytical results for the …
