Modulated Gauge Theories and Fracton Behavior in 2D

November 22, 2023 @ 4:00 pm - 5:30 pm

Quantum Matter Seminar

Speaker: Guilherme Delfino Silva (Boston University)

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.
