Quantum signatures of chaos in the dynamics of bipartite fluctuations

Qian Wang

We study the quantum signatures of chaos by using the concept of bipartite fluctuations in the kicked two-site Bose-Hubbard model, which can be mapped to the well-studied kicked to…

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…
