Role of interactions in ferrofluid thermal ratchets
Volker Becker Andreas Engel
Orientational fluctuations of colloidal particles with magnetic moments may be rectified with the help of external magnetic fields with suitably chosen time dependence. As a result…
Translations and Rotations are correlated in Granular Gases
Nikolai V. Brilliantov, Thorsten Poeschel, W. Till Kranz +1
In a granular gas of rough particles the axis of rotation is shown to be correlated with the translational velocity of the particles. The average relative orientation of angular an…
Bistability and noise-enhanced velocity of rolling motion
Thorsten Poeschel, Nikolai V. Brilliantov, Alexei Zaikin
We investigate the motion of a hard cylinder rolling down a soft inclined plane. The cylinder is subjected to a viscous drag force and stochastic fluctuations due to the surroundin…
Transient structures in a Granular Gas
Nikolai Brilliantov, Clara Saluena, Thomas Schwager +1
A force-free granular gas is considered with impact-velocity dependent coefficient of restitution as it follows from the model of viscoelastic particles. We analyze structure forma…
Hydrodynamics and transport coefficients for Granular Gases
Nikolai Brilliantov, Thorsten Poeschel
The hydrodynamics of granular gases of viscoelastic particles, whose collision is described by an impact-velocity dependent coefficient of restitution, is developed using a modifie…
