Classical nonintegrability of a quantum chaotic SU(3) Hamiltonian system
Adam Sawicki, Marek Kuś
We prove nonintegrability of a model Hamiltonian system defined on the Lie algebra suitable for investigation of connections between classical and quantum charact…

Searching for extremal PPT entangled states
Remigiusz Augusiak, Janusz Grabowski, Marek Kuś +1
We study extremality in various sets of states that have positive partial transposes. One of the tools we use for this purpose is the recently formulated criterion allowing to judg…

`Classical' quantum states
Marek Kuś, Ingemar Bengtsson
We show that several classes of mixed quantum states in finite-dimensional Hilbert spaces which can be characterized as being, in some respect, 'most classical' can be described an…
