Avoiding gauge ambiguities in cavity quantum electrodynamics

Abstract Systems of interacting charges and fields are ubiquitous in physics.Recently, it has been shown that Hamiltonians derived using different gauges can yield different physical results when matter degrees of freedom are truncated to a few low-lying energy eigenstates.This effect is particularly prominent in the ultra-strong coupling regime.Su
