Oscillations in Quantum Entanglement During Rescattering
Attila Czirjak, Szilard Majorosi, Judit Kovacs +1
We study the time evolution of quantum entanglement between an electron and its parent ion during the rescattering due to a strong few-cycle laser pulse. Based on a simple one-dime…
Time dependence of quantum entanglement in the collision of two particles
Mihaly G. Benedict, Judit Kovacs, Attila Czirjak
We follow the emergence of quantum entanglement in a scattering event between two initially uncorrelated distinguishable quantum particles interacting via a delta potential. We cal…
Exact density oscillations in the Tonks-Girardeau gas and their optical detection
Mihaly G. Benedict, Csaba Benedek, Attila Czirjak
We construct the exact time dependent density profile for a superposition of the ground and singly excited states of a harmonically trapped one dimensional Bose-Einstein condensate…
Decoherence of molecular wave packets in an anharmonic potential
Peter Foldi, Mihaly G. Benedict, Attila Czirjak +1
The time evolution of anharmonic molecular wave packets is investigated under the influence of the environment consisting of harmonic oscillators. These oscillators represent photo…
Preparation of decoherence-free, subradiant states in a cavity
Peter Foldi, Mihaly G. Benedict, Attila Czirjak
The cause of decoherence in a quantum system can be traced back to the interaction with the environment. As it has been pointed out first by Dicke, in a system of N two-level atoms…
Rapid and slow decoherence in conjunction with dissipation in a system of two-level atoms
Peter Foldi, Attila Czirjak, Mihaly G. Benedict
We investigate the time evolution of a superposition of macroscopically distinct quantum states in a system of two-level atoms interacting with a thermal environment of photon mode…
Wigner functions, squeezing properties and slow decoherence of atomic Schrodinger cats
M. G. Benedict, A. Czirjak
We consider a class of states in an ensemble of two-level atoms: a superposition of two distinct atomic coherent states, which can be regarded as atomic analogues of the states usu…
