Space-dependent symmetries and fractons

KT Grosvenor, C Hoyos, F Peña-Benítez… - Frontiers in …, 2022 - frontiersin.org
There has been a surge of interest in effective non-Lorentzian theories of excitations with
restricted mobility, known as fractons. Examples include defects in elastic materials, vortex …

Global dipole symmetry, compact Lifshitz theory, tensor gauge theory, and fractons

P Gorantla, HT Lam, N Seiberg, SH Shao - Physical Review B, 2022 - APS
We study field theories with global dipole symmetries and gauge dipole symmetries. The
famous Lifshitz theory is an example of a theory with a global dipole symmetry. We study in …

Subsystem non-invertible symmetry operators and defects

W Cao, L Li, M Yamazaki, Y Zheng - SciPost Physics, 2023 - scipost.org
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 …

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 …

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 …

Low-energy limit of some exotic lattice theories and UV/IR mixing

P Gorantla, HT Lam, N Seiberg, SH Shao - Physical Review B, 2021 - APS
We continue our exploration of exotic, gapless lattice and continuum field theories with
subsystem global symmetries. In an earlier paper, we presented free lattice models enjoying …

Breakdown of hydrodynamics below four dimensions in a fracton fluid

P Glorioso, J Guo, JF Rodriguez-Nieva, A Lucas - Nature Physics, 2022 - nature.com
Hydrodynamics is a universal effective theory that describes the thermalization of chaotic
many-body systems, and depends only on the symmetries of the underlying theory. Although …

[HTML][HTML] A modified Villain formulation of fractons and other exotic theories

P Gorantla, HT Lam, N Seiberg… - Journal of Mathematical …, 2021 - pubs.aip.org
We reformulate known exotic theories (including theories of fractons) on a Euclidean
spacetime lattice. We write them using the Villain approach, and then we modify them to a …

Anomaly inflow for subsystem symmetries

FJ Burnell, T Devakul, P Gorantla, HT Lam, SH Shao - Physical Review B, 2022 - APS
We study't Hooft anomalies and the related anomaly inflow for subsystem global symmetries.
These symmetries and anomalies arise in a number of exotic systems, including models with …

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 …
