Research Summary
Liangyu Chen studies quantum information in field theory and holography, especially how entanglement-based quantities diagnose deformed or chaotic quantum systems. His recent work on TTbar and JTbar deformed CFTs analyzes how symmetries, operators, and correlators survive or are reorganized under irrelevant deformations. Other projects on KdV ensembles, ETH, Renyi and reflected entropies, entanglement of purification, Krylov complexity, modular flow, and mutual information all address a common question: which information-theoretic observables remain sharp enough to probe nonlocal dynamics in strongly coupled or holographic field theories.
