Instanton expansions and phase transitions
Abstract A central object in any axionic theory is its periodic potential, which is typically generated by instantons. The goal of this paper is to understand what physically happens to the theory when we lose control of the potential’s instanton expansion. We argue, using the Yang-Lee theory of pha...
