Wall attraction and repulsion of hydrodynamically interacting particles
Steffen Schreiber, Jochen Bammert, Philippe Peyla +1
We investigate hydrodynamic interaction effects between colloidal particles in the vicinity of a wall in the low Reynolds-number limit. Hydrodynamically interacting pairs of beads…
Hydrodynamic attraction and repulsion between asymmetric rotors
Steffen Schreiber, Thomas Fischer, Walter Zimmermann
At low Reynolds numbers, the hydrodynamic interaction between dumbbells driven by an external rotating field can be attractive or repulsive. Dumbbells of dissimilar asymmetric shap…
Dumbbell diffusion in a spatially periodic potential
Jochen Bammert, Steffen Schreiber, Walter Zimmermann
We present a numerical investigation of the Brownian motion and diffusion of a dumbbell in a two-dimensional periodic potential. Its dynamics is described by a Langevin model inclu…
Nonanalyticities of the entropy induced by saddle points of the potential energy landscape
Michael Kastner, Oliver Schnetz, Steffen Schreiber
The relation between saddle points of the potential of a classical many-particle system and the analyticity properties of its Boltzmann entropy is studied. For finite systems, each…
Phase Transitions from Saddles of the Potential Energy Landscape
Michael Kastner, Oliver Schnetz, Steffen Schreiber
The relation between saddle points of the potential of a classical many-particle system and the analyticity properties of its thermodynamic functions is studied. For finite systems…
