Dynamics of Bose-Einstein Condensates in One-Dimensional Optical Lattices in the Presence of Transverse Resonances
K. -P. Marzlin, V. I. Yukalov
The dynamics of Bose-Einstein condensates in the lowest energy band of a one-dimensional optical lattice is generally disturbed by the presence of transversally excited resonant st…
Photon Channelling in Foams
Michael Schmiedeberg, MirFaez Miri, Holger Stark
Experiments by Gittings, Bandyopadhyay, and Durian [Europhys. Lett.\ \textbf{65}, 414 (2004)] demonstrate that light possesses a higher probability to propagate in the liquid phase…
Nonlinear rheology of dense colloidal dispersions: a phenomenological model and its connection to mode coupling theory
Matthias Fuchs, Matthias Ballauff
Rheological properties, especially 'shear-thinning', of dense colloidal dispersions are discussed on three different levels. A generalized phenomonological Maxwell model gives a br…
Nearly-logarithmic decay in the colloidal hard-sphere system
Matthias Sperl
Nearly-logarithmic decay is identified in the data for the mean-squared displacement of the colloidal hard-sphere system at the liquid-glass transition [v. Megen et. al, Phys. Rev.…
Synchronization of rotating helices by hydrodynamic interactions
M. Reichert, H. Stark
Some types of bacteria use rotating helical flagella to swim. The motion of such organisms takes place in the regime of low Reynolds numbers where viscous effects dominate and wher…
A criterion for membership in archimedean semirings
Markus Schweighofer
We prove an extension of the classical Real Representation Theorem (going back to Krivine, Stone, Kadison, Dubois and Becker and often called Kadison-Dubois Theorem). It is a crite…
