Coherent backscattering of light from saturated atoms
Vyacheslav Shatokhin, Thomas Wellens, Cord Müller +1
We survey recent progress achieved in understanding the impact of inelastic processes on coherent backscattering of light from cold atoms that are saturated by a powerful laser fie…
Information and entropy in quantum Brownian motion: Thermodynamic entropy versus von Neumann entropy
Christian Hoerhammer, Helmut Buettner
We compare the thermodynamic entropy of a quantum Brownian oscillator derived from the partition function of the subsystem with the von Neumann entropy of its reduced density matri…
Entanglement Witnesses from Single-Particle Interference
T. Scholak, F. Mintert, C. A. Müller
We describe a general method of realizing entanglement witnesses in terms of the interference pattern of a single quantum probe. After outlining the principle, we discuss specific…
Environment-induced two-mode entanglement in quantum Brownian motion
C. Hoerhammer, H. Buettner
The time evolution of quantum correlations of entangled two-mode continuous variable states is examined in single-reservoir as well as two-reservoir models, representing noisy corr…
Diffusive spin transport
Cord A. Mueller
Information to be stored and transported requires physical carriers. The quantum bit of information (qubit) can for instance be realised as the spin 1/2 degree of freedom of a mass…
Quantum Mechanical Heat Transport in Disordered Harmonic Chains
Christopher Gaul, Helmut Büttner
We investigate the mechanism of heat conduction in ordered and disordered harmonic onedimensional chains within the quantum mechanical Langevin method. In the case of the disordere…
