Topological spectral form factor reveals emergent non-Hermitian single-particle transitions from many-body quantum chaos
Daniel Harkin, Chun Y. Leung, Amos Chan
In equilibrium, topological defect insertions in quantum and classical partition functions provide non-perturbative probes of phase transitions beyond local observables. In non-equ…
Engineer coherent oscillatory modes in Markovian open quantum systems
Chun Hei Leung, Pak-Tik Fong, Tianyi Yan +1
We develop a novel framework to engineer persistent oscillatory modes in Markovian open quantum systems governed by a time-independent Lindblad master equation. We show that oscill…
Symmetries, Conservation Laws and Entanglement in Non-Hermitian Fermionic Lattices
Rafael D. Soares, Youenn Le Gal, Chun Y. Leung +3
Non-Hermitian quantum many-body systems feature steady-state entanglement transitions driven by the competition between unitary dynamics and dissipation. In this work, we reveal th…
Entanglement and operator correlation signatures of many-body quantum Zeno phases in inefficiently monitored noisy systems
Chun Y. Leung, Alessandro Romito
The interplay between information-scrambling Hamiltonians and local continuous measurements hosts platforms for exotic measurement-induced phase transition in out-of-equilibrium st…
Theory of free fermions dynamics under partial post-selected monitoring
Chun Y. Leung, Dganit Meidan, Alessandro Romito
Monitored quantum systems undergo Measurement-induced Phase Transitions (MiPTs) stemming from the interplay between measurements and unitary dynamics. When the detector readout is…
