Phase diffusion in a Bose-Einstein condensate of light

, 2014
We study phase diffusion in a Bose-Einstein condensate of light in a dye-filled optical microcavity, i.e., the spreading of the probability distribution for the condensate phase.

Polarizability and alignment of dielectric nanoparticles in an external electric field: Bowls, dumbbells, and cuboids

, 2011
We employ the coupled dipole method to calculate the polarizability tensor of various anisotropic dielectric clusters of polarizable atoms, such as cuboid-, bowl-, and dumbbell-shaped nanoparticles.

Communication: Bulkiness versus anisotropy: The optimal shape of polarizable Brownian nanoparticles for alignment in electric fields

, 2012
Self-assembly and alignment of anisotropic colloidal particles are important processes that can be influenced by external electric fields. However, dielectric nanoparticles are generally hard to align this way because of their small size and low ...

Collective diffusion of colloidal hard rods in smectic liquid crystals: effect of particle anisotropy

, 2010
We study the layer-to-layer diffusion in smectic-A liquid crystals of colloidal hard rods with different length-to-diameter ratios using computer simulations.

Popping the cork: mechanisms of phage genome ejection

, 2013
Sixty years after Hershey and Chase showed that nucleic acid is the major component of phage particles that is ejected into cells, we still do not fully understand how the process occurs. Advances in electron microscopy have revealed the structure of the

Controlling coherence via tuning of the population imbalance in a bipartite optical lattice

, 2014
The control of transport properties is a key tool at the basis of many technologically relevant effects in condensed matter. The clean and precisely controlled environment of ultracold atoms in optical lattices allows one to prepare simplified but ...

Stringlike clusters and cooperative interlayer permeation in smectic liquid crystals formed by colloidal rods

, 2009
Using simulations of hard rods in smectic-A states, we find stringlike clusters of up to 10 interlayer rods exhibiting dynamic cooperativity. We also find non-Gaussian diffusion and heterogeneous dynamics due to the equilibrium periodic smectic density ...

Phenomenology of current-skyrmion interactions in thin films with perpendicular magnetic anisotropy

, 2014
We study skyrmions in magnetic thin films with structural inversion asymmetry perpendicular to the film plane. We construct a phenomenological model that describes the interaction between the motion of skyrmions and electric currents to lowest order in ...

Phase fluctuations and first-order correlation functions of dissipative Bose-Einstein condensates

, 2014
We investigate the finite-lifetime effects on first-order correlation functions of dissipative Bose-Einstein condensates. By taking into account the phase fluctuations up to all orders, we show that the finite-lifetime effects are negligible for the ...
