Fluctuation-dissipation ratio in lattice-gas models with kinetic constraints

We investigate by Monte-Carlo simulation the linear response function of three dimensional structural glass models defined by short-range kinetic constraints and a trivial equilibrium Boltzmann-Gibbs measure. The breakdown of the fluctuation-dissipation theorem in the glassy phase follows the prediction of mean field low temperature mode-coupling theory.

Cooperative diffusion in weakly charged polyelectrolyte gels

A general expression for the cooperative diffusion constant of weakly charged gels is derived as a function of the thermodynamic parameters such as polyelectrolyte concentration, salt concentration, ionic strength, and the degree of crosslinking. In the low concentration range it decreases with the monomer concentration. Received: 30 January 1998 / Revised: 4 May 1998 / Accepted: 6 May 1998     

On the Fermi surface of some organic superconductors with sizeable critical temperatures

Recent studies of the Fermi surface of quasi-two-dimensional organic conductors comfort the idea that the presence of a van Hove anomaly near the Fermi level is a favourable factor for superconductivity. Received: 28 April 1998 / Revised and accepted: 13 May 1998     

Photo induced collisions with laser cooled He* atoms

This paper presents an experimental investigation of cold collisions between metastable helium atoms in an optical trap at 1 mK. Penning (PI) and associative (AI) ionization reactions are distinguished using a mass spectrometer and studied under influence of near resonant laser light. Dramatic enhancement, by more than a factor 15, of the ion rate is observed when the laser is tuned close to resonance. Experimental findings are well-described, on an absolute scale, by model predictions. Received: 9 February 1998 / Revised: 4 May 1998 / Accepted: 14 May 1998

Molecular resolution of an organic monolayer by dynamic AFM

We report molecularly resolved dynamic AFM-measurements of a monolayer of perylene-3,4,9,10-tetracarboxylic-3,4,9,10-dianhydride (PTCDA) epitaxially grown on Ag(110). Preparation and experiments were performed under UHV conditions. The frequency-modulation AFM technique was applied. Received: 26 February 1998 / Revised: 13 May 1998 / Accepted: 8 June 1998
