Description
Summary:The agenda of dissipative quantum chaos is to create a toolbox that would allow us to categorize open quantum systems into "chaotic"and "regular"ones. Two approaches to this categorization have been proposed recently. One of them is based on the spectral properties of generators of open quantum evolution. The other one utilizes the concept of Lyapunov exponents to analyze quantum trajectories obtained by unraveling this evolution. By using two quantum models, we relate the two approaches and try to understand whether there is an agreement between the corresponding categorizations. Our answer is affirmative. © 2022 Author(s).
