Quantum Correlations in Two-Fermion Systems
John Schliemann, J. Ignacio Cirac, Marek Kus +2
We characterize and classify quantum correlations in two-fermion systems having 2K single-particle states. For pure states we introduce the Slater decomposition and rank (in analog…
Classical 1D maps, quantum graphs and ensembles of unitary matrices
Prot Pakonski, Karol Zyczkowski, Marek Kus
We study a certain class of classical one dimensional piecewise linear maps. For these systems we introduce an infinite family of Markov partitions into equal cells. The symbolic d…
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…
Level Dynamics and Universality of Spectral Fluctuations
Peter Braun, Sven Gnutzmann, Fritz Haake +2
The spectral fluctuations of quantum (or wave) systems with a chaotic classical (or ray) limit are mostly universal and faithful to random-matrix theory. Taking up ideas of Pechuka…
