On the relation between states and maps in infinite dimensions
Janusz Grabowski, Marek Kus, Giuseppe Marmo
Relations between states and maps, which are known for quantum systems in finite-dimensional Hilbert spaces, are formulated rigorously in geometrical terms with no use of coordinat…
Separability, entanglement and full families of commuting normal matrices
Jan Samsonowicz, Marek Kus, Maciej Lewenstein
We reduce the question whether a given quantum mixed state is separable or entangled to the problem of existence of a certain full family of commuting normal matrices whose matrix…
Level dynamics and the ten-fold way
Alan T. Huckleberry, Marek Kus, Patrick Schuetzdeller
We investigate the parameter dynamics of eigenvalues of Hamiltonians ('level dynamics') defined on symmetric spaces relevant for condensed matter and particle physics. In particula…
