Complexity of quantum motion and quantum-classical correspondence: A phase-space approach
Jiaozi Wang, Giuliano Benenti, Giulio Casati +1
We discuss the connection between the out-of-time-ordered correlator and the number of harmonics of the phase-space Wigner distribution function. In particular, we show that both q…
Chaotic diffusion of complex trajectory and its quantum signature
Wen-Lei Zhao, Pengkai Gong, Jiaozi Wang +1
We investigate both the quantum and classical dynamics of a non-Hermitian system via a kicked rotor model with symmetry. For the quantum dynamics, both the mean mome…
Steady-state relations for a two-level system locally and relatively-strongly coupled to a generic many-body quantum chaotic environment
Hua Yan, Jiaozi Wang, Wen-ge Wang
We study the long-time average of the reduced density matrix (RDM) of a two-level system as the central system, which is locally coupled to a generic many-body quantum chaotic syst…
Convergent perturbation expansion of energy eigenfunctions on unperturbed basis states in classically-forbidden regions
Jiaozi Wang, Wen-ge Wang
We study properties of eigenfunctions of perturbed systems, given on the eigenbases of unperturbed, integrable systems. For a given pair of perturbed and unperturbed systems, with…
Directed momentum current induced by the PT-symmetric driving
Wen-Lei Zhao, Jiaozi Wang, Xiaohui Wang +1
We investigate the directed momentum current in the quantum kicked rotor model with symmetric deriving potential. For the quantum non-resonance case, the values of q…
