Space-dependent symmetries and fractons
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
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 …

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

Spontaneous breaking of multipole symmetries
Multipole symmetries are of interest both as a window on fracton physics and as a crucial
ingredient in realizing new universality classes for quantum dynamics. Here we address the …

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 …
