Phase transition from eigenstate thermalization: forbidden singularity and instanton proliferation via AGT correspondence
Yongjiang Xu, Weixin Sun, Chushun Tian +1
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 ma…

Lee-Yang paradigm of phase transition in eigenstate thermalized systems
Yongjiang Xu, Weixin Sun, Chushun Tian +1
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 di…

Non-perturbative aspects of entanglement structures in -deformed CFTs
Wen-Xin Lai, Huajia Wang, Yongjiang Xu
Turning on the -deformation in a two-dimensional CFT provides a unique window to study explicitly how non-local features arise in the UV as a result of the deformation. A…
