Different Traces of Quantum Systems Having the Same Classical Limit
Prot Pakonski
Many quantum systems may have the same classical limit. We argue that in the classical limit their traces do not necessarily converge one to another. The trace formula allows to ex…

Dynamical entropy for systems with stochastic perturbation
Andrzej Ostruszka, Prot Pakonski, Wojciech Slomczynski +1
Dynamics of deterministic systems perturbed by random additive noise is characterized quantitatively. Since for such systems the KS-entropy diverges we analyse the difference betwe…

Quantum baker map on the sphere
Prot Pakonski, Andrzej Ostruszka, Karol Zyczkowski
We define a class of dynamical systems on the sphere analogous to the baker map on the torus. The classical maps are characterized by dynamical entropy equal to ln 2. We construct…
