Superdiffusion in a Honeycomb Billiard
Michael Schmiedeberg, Holger Stark
We investigate particle transport in the honeycomb billiard that consists of connected channels placed on the edges of a honeycomb structure. The spreading of particles is superdif…
Yield Stress Discontinuity in a Simple Glass
Fathollah Varnik, Oliver Henrich
Large scale molecular dynamics simulations are performed to study the steady state yielding dynamics of a well established simple glass. In contrast to the supercooled state, where…
Poisson-Bracket Approach to the Dynamics of Nematic Liquid Crystals. The Role of Spin Angular Momentum
H. Stark, T. C. Lubensky
Nematic liquid crystals are well modeled as a fluid of rigid rods. Starting from this model, we use a Poisson-bracket formalism to derive the equations governing the dynamics of ne…
Observation of the critical regime near Anderson localization of light
Martin Störzer, Peter Gross, Christof M. Aegerter +1
Diffusive transport is among the most common phenomena in nature [1]. However, as predicted by Anderson [2], diffusion may break down due to interference. This transition from diff…
Phase transitions in one dimension: are they all driven by domain walls?
N. Theodorakopoulos
Two known distinct examples of one-dimensional systems which are known to exhibit a phase transition are critically examined: (A) a lattice model with harmonic nearest-neighbor ela…
Control of topography, stress and diffusion at molecule-metal interface
Nikolai B. Zhitenev, Weirong Jiang, Artur Erbe +4
Transport properties of metal-molecule-metal junctions containing monolayer of conjugated and saturated molecules with characteristic dimensions in the range of 30-300 nm are corre…
