Anomalous entanglement scaling from eigenvector nonorthogonality in critical non-Hermitian free fermions
Zhenyu Xiao, Shinsei Ryu
Entanglement carries universal content that labels phases and critical points. We study the entanglement entropy of the steady states of critical non-Hermitian free-fermion chains.…

Non-Hermitian Disordered Systems
Kohei Kawabata, Shinsei Ryu
Non-Hermitian disordered systems have emerged as a central arena in modern physics, with ramifications spanning condensed matter, quantum, statistical, and high energy contexts. Th…
