Quantum Breakdown Condensate: A Disorder-Free Quantum Glass

This paper introduces a novel phase of matter, the quantum breakdown condensate, which behaves like a disorder-free quantum glass. It's significant because it challenges existing classifications of phases and presents a new perspective on quantum systems with spontaneous symmetry breaking. The use of exact diagonalization and analysis of the model's properties, including its edge modes, order parameter, and autocorrelations, provides strong evidence for this new phase. The finding of a finite entropy density and a first-order phase transition is particularly noteworthy.
