Non-Markovian master equations from entanglement with stationary unobserved degrees of freedom

Adrian A. Budini, Henning Schomerus

We deduce a class of non-Markovian completely positive master equations which describe a system in a composite bipartite environment, consisting of a Markovian reservoir and additi…

Concurrence of quasi pure quantum states

Florian Mintert, Andreas Buchleitner

We derive an analytic approximation for the concurrence of weakly mixed bipartite quantum states - typical objects in state of the art experiments. This approximation is shown to b…

Molecular effects in the ionization of N, O and F by intense laser fields

Daniel Dundas, Jan M. Rost

In this paper we study the response in time of N, O and F to laser pulses having a wavelength of 390nm. We find single ionization suppression in O and its absence i…

Concurrence of mixed multi-partite quantum states

Florian Mintert, Marek Kus, Andreas Buchleitner

We propose generalizations of concurrence for multi-partite quantum systems that can distinguish qualitatively distinct quantum correlations. All introduced quantities can be evalu…

Decoherence and multipartite entanglement

André R. R. Carvalho, Florian Mintert, Andreas Buchleitner

We study the dynamics of multipartite entanglement under the influence of decoherence. A suitable generalization of concurrence reveals distinct scaling of the entanglement decay r…

Web-assisted tunneling in the kicked harmonic oscillator

André R. R. Carvalho, Andreas Buchleitner

We show that heating of harmonically trapped ions by periodic delta kicks is dramatically enhanced at isolated values of the Lamb-Dicke parameter. At these values, quasienergy eige…
