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…
Coexistence of directed momentum current and ballistic energy diffusion in coupled non-Hermitian kicked rotors
Jian-Zheng Li, Wen-Lei Zhao, Jie Liu
We numerically investigate the quantum transport in a coupled kicked rotors with the -symmetric potential. We find that the spontaneous -symmetry breaki…
Energy transfer, weak resonance, and Fermi's golden rule in Hamiltonian nonlinear Klein-Gordon equations
Zhen Lei, Jie Liu, Zhaojie Yang
This paper focuses on a class of nonlinear Klein-Gordon equations in three dimensions, which are Hamiltonian perturbations of the linear Klein-Gordon equation with potential. The u…
Landau damping effects in the synchronization of conformist and contrarian oscillators
Tian Qiu, Yue Zhang, Jie Liu +4
Two decades ago, a phenomenon resembling Landau damping was described in the synchronization of globally coupled oscillators: the evidence of a regime where the order parameter dec…
