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 …

Snowmass white paper: Generalized symmetries in quantum field theory and beyond

C Cordova, TT Dumitrescu, K Intriligator… - arxiv preprint arxiv …, 2022 - arxiv.org
Symmetry plays a central role in quantum field theory. Recent developments include
symmetries that act on defects and other subsystems, and symmetries that are categorical …

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 …

Quantum Liquids: Emergent higher-rank gauge theory and fractons

Y You - Annual Review of Condensed Matter Physics, 2024 - annualreviews.org
Fractons emerge from many-body systems, featuring subdimensional particles with
restricted mobility. These particles have attracted interest for their roles across disciplines …

Exotic symmetries, duality, and fractons in 2+ 1-dimensional quantum field theory

N Seiberg, SH Shao - SciPost Physics, 2021 - scipost.org
We discuss nonstandard continuum quantum field theories in 2+ 1 dimensions. They exhibit
exotic global symmetries, a subtle spectrum of charged excitations, and dualities similar to …

Anomalous diffusion in dipole-and higher-moment-conserving systems

J Feldmeier, P Sala, G De Tomasi, F Pollmann… - Physical Review Letters, 2020 - APS
The presence of global conserved quantities in interacting systems generically leads to
diffusive transport at late times. Here, we show that systems conserving the dipole moment …

Exotic symmetries, duality, and fractons in 3+1-dimensional quantum field theory

N Seiberg, SH Shao - SciPost Physics, 2020 - scipost.org
We extend our exploration of nonstandard continuum quantum field theories in 2+ 1
dimensions to 3+ 1 dimensions. These theories exhibit exotic global symmetries, a peculiar …

Fractonic Luttinger liquids and supersolids in a constrained Bose-Hubbard model

P Zechmann, E Altman, M Knap, J Feldmeier - Physical Review B, 2023 - APS
Quantum many-body systems with fracton constraints are widely conjectured to exhibit
unconventional low-energy phases of matter. In this paper, we demonstrate the existence of …

Field theories with a vector global symmetry

N Seiberg - SciPost Physics, 2020 - scipost.org
Motivated by recent discussions of fractons, we explore nonrelativistic field theories with a
continuous global symmetry, whose charge is a spatial vector. We present several such …

Towards classification of Fracton phases: the multipole algebra

A Gromov - Physical Review X, 2019 - APS
We present an effective field theory approach to the fracton phases. The approach is based
on the notion of a multipole algebra. It is an extension of space (time) symmetries of a …
