Quantum criticality at the boundary of the non-Hermitian regime of a Floquet system
Wen-Lei Zhao, Jie Liu
We investigate both analytically and numerically the dynamics of quantum scrambling, characterized by the out-of-time ordered correlators (OTOCs), in a non-Hermitian quantum kicked…
Super-exponential behaviors of out-of-time ordered correlators and Loschmidt echo in a non-Hermitian interacting system
Wen-Lei Zhao, Chao Han, Han Ke +1
We investigate the out-of-time ordered correlators and Loschmidt echo in a non-Hermitian interacting system governed by a Gross-Pitaevskii map model, which incorporates a periodica…
Caustic effects on the high-order harmonic generation in graphene
Fulong Dong, Qinzhi Xia, Jie Liu
We employ the two-band density-matrix equations and time-dependent density functional theory to calculate high-order harmonic generation (HOHG) in graphene under a femtosecond lase…
Scaling laws of the out-of-time-order correlators at the transition to the spontaneous -symmetry breaking in a Floquet system
Wen-Lei Zhao, Ru-Ru Wang, Han Ke +1
We investigate both numerically and analytically the dynamics of out-of-time-order correlators (OTOCs) in a non-Hermitian kicked rotor model, addressing the scaling laws of the tim…
Topological Phases on Quantum Trees
Alex Westström, Wenbu Duan, Kangpei Yao +3
In this work, we present a theory for topological phases for quantum systems on tree graphs. Conventionally, topological phases of matter have been studied in regular lattices, but…
