Soft electrowetting
Ranabir Dey, Mathijs van Gorcum, Frieder Mugele +1
Electrowetting is a commonly used tool to manipulate sessile drops on hydrophobic surfaces. By applying an external voltage over a liquid and a dielectric-coated surface, one achie…
Enlargeability and index theory: Infinite covers
Bernhard Hanke, Thomas Schick
In a previous paper, we showed nonvaninishing of the universal index elements in the K-theory of the maximal C*-algebras of the fundamental groups of enlargeable spin manifolds. Th…
Completions of countable non-standard models of Q
Peter Laubenheimer, Thomas Schick, Ulrich Stuhler
In this note, we study non-standard models of the rational numbers with countably many elements. These are ordered fields, and so it makes sense to complete them, using non-standar…
Stellar Populations of a Sample of Tidal Dwarf Galaxies
Peter M. Weilbacher, Uta Fritze-v. Alvensleben, Pierre-Alain Duc
We investigate the stellar populations of a sample of Tidal Dwarf Galaxies, combining observations and evolutionary synthesis models to try and reveal their formation mechanism. On…
Diffraction of Weakly Bound Clusters: Spectroscopy and Size Effects
Martin Stoll, Thorsten Koehler, Gerhard C. Hegerfeldt
Exciting experiments in the field of atom and molecule optics have lately drawn much attention to the effects involved in the coherent diffraction of particle beams. We review the…
Operator algebras and topology
Thomas Schick
These notes cover the contents of three survey lectures held at the ICTP Trieste Summer school on High dimensional manifold theory 2001. They introduce techniques coming from the t…
