Magic transition in monitored free fermion dynamics
Cheng Wang, Zhi-Cheng Yang, Tianci Zhou +1
We investigate magic and its connection to entanglement in 1+1 dimensional random free fermion circuits, with a focus on hybrid free fermion dynamics that can exhibit an entangleme…

Exponentially slow thermalization in 1D fragmented dynamics
Cheng Wang, Shankar Balasubramanian, Yiqiu Han +3
We investigate the thermalization dynamics of 1D systems with local constraints coupled to an infinite temperature bath at one boundary. The coupling to the bath eventually erases…

Yang-Lee edge singularity triggered entanglement transition
Shao-Kai Jian, Zhi-Cheng Yang, Zhen Bi +1
We show that a class of symmetric non-Hermitian Hamiltonians realizing the Yang-Lee edge singularity exhibits an entanglement transition in the long-time steady stat…
