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 …

Fractons

RM Nandkishore, M Hermele - Annual Review of Condensed …, 2019 - annualreviews.org
Fracton phases constitute a new class of quantum state of matter. They are characterized by
excitations that exhibit restricted mobility, being either immobile under local Hamiltonian …

Ergodicity breaking arising from Hilbert space fragmentation in dipole-conserving Hamiltonians

P Sala, T Rakovszky, R Verresen, M Knap, F Pollmann - Physical Review X, 2020 - APS
We show that the combination of charge and dipole conservation—characteristic of fracton
systems—leads to an extensive fragmentation of the Hilbert space, which, in turn, can lead …

Fracton-elasticity duality

M Pretko, L Radzihovsky - Physical review letters, 2018 - APS
Motivated by recent studies of fractons, we demonstrate that elasticity theory of a two-
dimensional quantum crystal is dual to a fracton tensor gauge theory, providing a concrete …

Localization in fractonic random circuits

S Pai, M Pretko, RM Nandkishore - Physical Review X, 2019 - APS
We study the spreading of initially local operators under unitary time evolution in a one-
dimensional random quantum circuit model that is constrained to conserve a U (1) charge …

Foliated quantum field theory of fracton order

K Slagle - Physical Review Letters, 2021 - APS
We introduce a new kind of foliated quantum field theory (FQFT) of gapped fracton orders in
the continuum. FQFT is defined on a manifold with a layered structure given by one or more …

Fracton topological order from the Higgs and partial-confinement mechanisms of rank-two gauge theory

H Ma, M Hermele, X Chen - Physical Review B, 2018 - APS
Fractons are gapped pointlike excitations in d= 3 topological ordered phases whose motion
is constrained. They have been discovered in several gapped models but a unifying …

Cage-net fracton models

A Prem, SJ Huang, H Song, M Hermele - Physical Review X, 2019 - APS
We introduce a class of gapped three-dimensional models, dubbed “cage-net fracton
models,” which host immobile fracton excitations in addition to non-Abelian particles with …

Emergent phases of fractonic matter

A Prem, M Pretko, RM Nandkishore - Physical Review B, 2018 - APS
Fractons are emergent particles which are immobile in isolation, but which can move
together in dipolar pairs or other small clusters. These exotic excitations naturally occur in …

Symmetric tensor gauge theories on curved spaces

K Slagle, A Prem, M Pretko - Annals of Physics, 2019 - Elsevier
Fractons and other subdimensional particles are an exotic class of emergent quasi-particle
excitations with severely restricted mobility. A wide class of models featuring these quasi …
