Mermin-Wagner theorems for quantum systems with multipole symmetries

Mathematical Physics 2026-02-02 v1 math.MP

Abstract

We prove Mermin-Wagner-type theorems for quantum lattice systems in the presence of multipole symmetries. These theorems show that the presence of higher-order symmetries protects against the breaking of lower-order ones. In particular, we prove that the critical dimension in which the charge symmetry can be broken increases if the system admits higher multipole symmetries, e.g. d=4 d = 4 on the regular lattice Zd \mathbb{Z}^d in the presence of dipole symmetry.
