Analysis
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.
Key Takeaways
- •Introduces a new phase of matter: the quantum breakdown condensate.
- •The condensate exhibits spontaneous symmetry breaking (SSB) with a finite entropy density.
- •The condensate behaves as a disorder-free quantum glass.
- •The model is analyzed using exact diagonalization and large S limit analysis.
- •The condensate's order parameter is effectively random due to the chaotic Bernoulli map.
Reference
“The condensate has an SSB order parameter being the local in-plane spin, which points in angles related by the chaotic Bernoulli (dyadic) map and thus is effectively random.”
