On determination of statistical properties of spectra from parametric level dynamics
Miroslaw Hardej, Marek Kus, Cezary Gonera +1
We analyze an approach aiming at determining statistical properties of spectra of time-periodic quantum chaotic system based on the parameter dynamics of their quasienergies. In pa…
Evaluable multipartite entanglement measures: are multipartite concurrences entanglement monotones?
Rafal Demkowicz-Dobrzanski, Andreas Buchleitner, Marek Kus +1
We discuss the monotonicity under local operations and classical communication (LOCC) of systematically constructed quantities aiming at quantification of entanglement properties o…
Constructing the classical limit for quantum systems on compact semisimple Lie algebras
I. Schafer, M. Kus
We give a general construction for the classical limit of a quantum system defined in terms of generators of an arbitrary compact semisimple Lie algebra, generalizing known results…
Symmetries, group actions, and entanglement
Janusz Grabowski, Marek Kus, Giuseppe Marmo
We address several problems concerning the geometry of the space of Hermitian operators on a finite-dimensional Hilbert space, in particular the geometry of the space of density st…
