Title: Modulated Gauge Theories and Fracton Behavior in 2D
Abstract: In this talk we investigate deconfined phases of
two-dimensional ZN lattice gauge theories associated to spatially
modulated symmetries. In order to study the low-energy physics of such
modulated gauge theories we propose and explore exactly solvable
gapped Hamiltonians, which allow us to fully characterize their
low-energy properties at zero temperature. We provide explicit
examples and discuss how non-polynomial symmetries, as exponential
symmetries, are powerful enough to fully constrain the mobility of
isolated excitations.
