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…

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…

Localization of nonlinear excitations in curved waveguides
Yu. B. Gaididei, P. L. Christiansen, P. G. Kevrekidis +2
Motivated by the example of a curved waveguide embedded in a photonic crystal, we examine the effects of geometry in a ``quantum channel'' of parabolic form. We study the linear ca…
