Correlations in multithermostat Brownian systems with Lorentz force

Abdoli, Iman ; Kalz, Erik ; Vuijk, Hidde D. ; Wittmann, René ; Sommer, Jens-Uwe ; Brader, Joseph M. ; Sharma, Abhinav

We study the motion of a Brownian particle subjected to Lorentz force due to an external magnetic field. Each spatial degree of freedom of the particle is coupled to a different thermostat. We show that the magnetic field results in correlation between different velocity components in the stationary state. Integrating the velocity autocorrelation matrix, we obtain the diffusion matrix that...

Nondiffusive fluxes in a Brownian system with Lorentz force

The Fokker-Planck equation provides a complete statistical description of a particle undergoing random motion in a solvent. In the presence of Lorentz force due to an external magnetic field, the Fokker-Planck equation picks up a tensorial coefficient, which reflects the anisotropy of the particle's motion. This tensor, however, cannot be interpreted as a diffusion tensor; there are...
