Ratcheting up energy by means of measurement
L. S. Schulman, B. Gaveau
The destruction of quantum coherence can pump energy into a system. For our examples this is paradoxical since the destroyed correlations are ordinarily considered negligible. Math…
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…
Dynamics of Loschmidt echoes and fidelity decay
Thomas Gorin, Tomaz Prosen, Thomas H. Seligman +1
Fidelity serves as a benchmark for the relieability in quantum information processes, and has recently atracted much interest as a measure of the susceptibility of dynamics to pert…
Phase rigidity and avoided level crossings in the complex energy plane
E. N. Bulgakov, I. Rotter, A. F. Sadreev
We consider the effective Hamiltonian of an open quantum system, its biorthogonal eigenfunctions and define the value that characterizes the phase…
Saturation of fidelity in the atom-optics kicked rotor
Sandro Wimberger, Andreas Buchleitner
We show that the quantum fidelity is accessible to cold atom experiments for a large class of evolutions in periodical potentials, properly taking into account the experimental ini…
Elastic vs. inelastic coherent backscattering of laser light by cold atoms: a master equation treatment
Vyacheslav Shatokhin, Cord A. Müller, Andreas Buchleitner
We give a detailed derivation of the master equation description of the coherent backscattering of laser light by cold atoms. In particular, our formalism accounts for the nonpertu…
