Quantum chaos in the spin coherent state representation
Marek Kuś, Robert Przybycień
We use spin coherent states to compare classical and quantum evolution of a simple paradigmatic, discrete-time quantum dynamical system exhibiting chaotic behavior in the classical…
Calogero-Moser models with internal degrees of freedom revisited
Katarzyna Kowalczyk-Murynka, Marek Kuś
We discuss various examples of classical Calogero-Moser models with internal degrees of freedom. These models besides of having some attractive properties, like the complete integr…
Lie groupoids in information geometry
Katarzyna Grabowska, Janusz Grabowski, Marek Kuś +1
We demonstrate that the proper general setting for contrast (potential) functions in statistical and information geometry is the one provided by Lie groupoids and Lie algebroids. T…
Geometry of quantum systems: density states and entanglement
Janusz Grabowski, Marek Kuś, Giuseppe Marmo
Various problems concerning the geometry of the space $u^*(\cH)$ of Hermitian operators on a Hilbert space $\cH$ are addressed. In particular, we study the canonical Poisson and Ri…
