Dariusz Chruscinski, Jacek Jurkowski, Andrzej Kossakowski
We construct a large class of bipartite M x N quantum states which defines a proper subset of states with positive partial transposes (PPT). Any state from this class is PPT but th…

Memory in a nonlocally damped oscillator
Dariusz Chruscinski, Jacek Jurkowski
We analyze the new equation of motion for the damped oscillator. It differs from the standard one by a damping term which is nonlocal in time and hence it gives rise to a system wi…
