Notes on false vacuum decay in quantum Ising models
arXiv:2510.12592
Abstract
This paper aims to gather together some of the basic ideas behind the theory of false vacuum decay in quantum Ising models, focusing on the application of spin chains as analogue systems to false vacuum decay in elementary particle theory. Elementary results on quantum Ising models are reformulated and extended to more closely resemble the theory of false vacuum decay in quantum field theory. The dynamics of bubble walls is investigated, and a speculative conjecture for the false vacuum decay rate in a two dimensional quantum Ising model is put forward.
