Anomalous correlation-induced dynamical phase transitions
Niaz Ali Khan, Pei Wang, Munsif Jan +1
The nonanalyticity of the Loschmidt echo at critical times in quantum quenched systems is termed as the dynamical quantum phase transition, extending the notion of quantum critical…

Stable real-energy spectral dynamics with topological transitions and non-Hermitian many-body localization
Shujie Cheng, Xixi Feng, Wen Chen +2
In this work, the interplay between non-Hermiticity, quasi-disorder, and repulsive interaction is studied for hard-core bosons confined in a one-dimensional optical lattice, where…
