Phase transition from eigenstate thermalization: forbidden singularity and instanton proliferation via AGT correspondence

Kavli Affiliate: Huajia Wang | Summary:In theoretical physics, finding connections between problems that appear in distinct contexts is an important way to leapfrog progresses, often by illuminating deep aspects that may otherwise seem obscure. In this paper, we consider in 2d CFTs the phenomenon of forbidden singularities in auto-correlation functions — a key signature of […]

Lee-Yang paradigm of phase transition in eigenstate thermalized systems

Kavli Affiliate: Huajia Wang | Summary:As phase transitions in isolated quantum systems remain elusive, here we show how a thermodynamic-like phase transition, falling into the Lee-Yang paradigm, can arise in systems displaying eigenstate thermalization. Specifically, we show that in holographic conformal field theories, the eigenstate expectation of the auto-correlation function can be mapped to the […]
