Exact Lindbladian Dynamics from Conformal Embeddings and Topological Defects in Conformal Field Theory
Chen Bai
Analyzing the dynamics of physical observables in open quantum many-body systems is a fundamental but highly challenging task that has yielded very few exact results. In this work,…

Relaxation Process During Complex Time Evolution In Two-Dimensional Integrable and Chaotic CFTs
Chen Bai, Weibo Mao, Masahiro Nozaki +2
We investigate the complex time evolution of a vacuum state with the insertion of a local primary operator in two-dimensional conformal field theories (2d CFTs). This complex time…

Spatially Structured Entanglement from Nonequilibrium Thermal Pure States
Chen Bai, Mao Tian Tan, Bastien Lapierre +1
We study quantum quench dynamics in (1+1)-dimensional critical systems, starting from thermal pure states called crosscap states, and evolving them under spatially inhomogeneous Ha…
