Dipole Oscillations of a Bose-Einstein Condensate in Presence of Defects and Disorder

, 2008
We consider dipole oscillations of a trapped dilute Bose-Einstein condensate in the presence of a scattering potential consisting either in a localized defect or in an extended disordered potential.

Statistics of resonance states in a weakly open chaotic cavity [PDF]

, 2010
In this letter, we demonstrate that a non-Hermitian Random Matrix description can account for both spectral and spatial statistics of resonance states in a weakly open chaotic wave system with continuously distributed losses.

Low-temperature quantum fluctuations in overdamped ratchets

, 2010
At low temperatures and strong friction the time evolution of the density distribution in position follows a quantum Smoluchowski equation. Recently, also higher-order contributions of quantum fluctuations to drift and diffusion coefficients have been ...

Quantum dissociation of a vortex-antivortex pair in a long Josephson junction

, 2003
We report a theoretical analysis and experimental observation of the quantum dynamics of a single vortex-antivortex (VAV) pair confined in a long narrow annular Josephson junction.

Statistics of resonances and of delay times in quasiperiodic Schr"odinger equations

, 2000
We study the statistical distributions of the resonance widths ${\cal P} (\Gamma)$, and of delay times ${\cal P} (\tau)$ in one dimensional quasi-periodic tight-binding systems with one open channel.

On the density of states and extinction mean free path of waves in random media: Dispersion relations and sum rules

, 2008
We establish a fundamental relationship between the averaged density of states and the extinction mean free path of wave propagating in random media. From the principle of causality and the Kramers-Kronig relations, we show that both quantities are ...

Low-Temperature Mobility of Surface Electrons and Ripplon-Phonon Interaction in Liquid Helium

, 2010
The low-temperature dc mobility of the two-dimensional electron system localized above the surface of superfluid helium is determined by the slowest stage of the longitudinal momentum transfer to the bulk liquid, namely, by the interaction of surface and
