Symmetry and Topology of Monitored Quantum Dynamics
Zhenyu Xiao, Kohei Kawabata
The interplay between unitary dynamics and quantum measurements induces diverse phenomena in open quantum systems with no counterparts in closed quantum systems at equilibrium. Her…
Simulational and theoretical studies of the Anderson transition in the chiral symmetry classes with weak topology
Shiyin Kuang, Tong Wang, Zhenyu Xiao +2
Combining lattice model simulations with a field theory study of effective theories, we investigate the nature of the Anderson transition in chiral symmetry classes with one-dimens…
Universal Stochastic Equations of Monitored Quantum Dynamics
Zhenyu Xiao, Tomi Ohtsuki, Kohei Kawabata
We investigate the monitored quantum dynamics of Gaussian mixed states and derive the universal Fokker-Planck equations that govern the stochastic time evolution of entire density-…
Topological effect on the Anderson transition in chiral symmetry classes
Pengwei Zhao, Zhenyu Xiao, Yeyang Zhang +1
In this Letter, we propose a mechanism of an emergent quasi-localized phase in chiral symmetry classes, where wave function along a spatial direction with weak topology is delocali…
