Universal and Maximal Entanglement Swapping in General Fermionic Gaussian States
Jiyuan Fang, Qicheng Tang, Xueda Wen
Exploring universal entanglement structure in many-body systems is both fundamental and challenging, particularly when the system undergoes non-unitary operations. In this work, we…

Dissipation meets conformal interface in open quantum systems: How the relaxation rate is suppressed
Ruhanshi Barad, Qicheng Tang, Xueda Wen
Conformal interfaces play an important role in quantum critical systems. In closed systems, the transmission properties of conformal interfaces are typically characterized by two q…

Phase Transitions in Quasi-Periodically Driven Quantum Critical Systems: Analytical Results
Jiyuan Fang, Qi Zhou, Xueda Wen
In this work, we study analytically the phase transitions in quasi-periodically driven one dimensional quantum critical systems that are described by conformal field theories (CFTs…
