Wigner function non-classicality as indicator of quantum chaos
A. Kowalewska-Kudłaszyk, J. K. Kalaga, W. Leoński
We propose a Wigner function based parameter that can be used as an indicator of quantum chaos. This parameter is defined as "entropy" from the time-dependence of "non-classicallit…

Long-time fidelity and chaos for a kicked nonlinear oscillator system
A. Kowalewska-Kudłaszyk, J. K. Kalaga, W. Leoński
We deal with a system comprising a nonlinear (Kerr-like) oscillator excited by a series of ultra-short external pulses. We introduce the fidelity-based entropic parameter that can…
