Statistical-mechanical description of quantum entanglement
J. K. Korbicz, F. Hulpke, A. Osterloh +1
We present a description of finite dimensional quantum entanglement, based on a study of the space of all convex decompositions of a given density matrix. On this space we construc…
Entanglement in Many-Body Systems
Luigi Amico, Rosario Fazio, Andreas Osterloh +1
The recent interest in aspects common to quantum information and condensed matter has prompted a prosperous activity at the border of these disciplines that were far distant until…
Integrable spin-boson models descending from rational six-vertex models
L. Amico, H. Frahm, A. Osterloh +1
We construct commuting transfer matrices for models describing the interaction between a single quantum spin and a single bosonic mode using the quantum inverse scattering framewor…
Robustness of adiabatic passage trough a quantum phase transition
Andrea Fubini, Giuseppe Falci, Andreas Osterloh
We analyze the crossing of a quantum critical point based on exact results for the transverse XY model. In dependence of the change rate of the driving field, the evolution of the…
