Classical analysis of correlated multiple ionization in strong fields
Bruno Eckhardt, Krzysztof Sacha
We discuss the final stages of the simultaneous ionization of two or more electrons due to a strong laser pulse. An analysis of the classical dynamics suggests that the dominant pa…
Dynamics of quantum entanglement
Karol Zyczkowski, Pawel Horodecki, Michal Horodecki +1
A model of discrete dynamics of entanglement of bipartite quantum state is considered. It involves a global unitary dynamics of the system and periodic actions of local bistochasti…
Monge Metric on the Sphere and Geometry of Quantum States
Karol Zyczkowski, Wojciech Slomczynski
Topological and geometrical properties of the set of mixed quantum states in the N-dimensional Hilbert space are analysed. Assuming that the corresponding classical dynamics takes…
Unconditional Pointer States from Conditional Master Equations
D. A. R. Dalvit, J. Dziarmaga, W. H. Zurek
When part of the environment responsible for decoherence is used to extract information about the decohering system, the preferred {\it pointer states} remain unchanged. This concl…
Geometry of entangled states
Marek Kus, Karol Zyczkowski
Geometric properties of the set of quantum entangled states are investigated. We propose an explicit method to compute the dimension of local orbits for any mixed state of the gene…
