Odd transport in a two-temperature Brownian dimer
Iman Abdoli, Hartmut Löwen
We investigate a two-temperature Brownian dimer with odd mobility, characterized by antisymmetric transport coefficients, as a controlled paradigm for odd nonequilibrium dynamics.…
Quadrupolar gyration of a Brownian particle in a confining ring
Iman Abdoli, Hartmut Löwen
We develop a minimal theoretical model that reveals a structured steady-state flux field with four alternating local circulation, a phenomenon we refer to as quadrupolar gyration.…
Enhanced Efficiency in Shear-Loaded Brownian Gyrators
Iman Abdoli, Abhinav Sharma, Hartmut Löwen
A Brownian gyrator is a system in which a particle experiences thermal noise from two distinct heat baths. This nonequilibrium setup inherently generates a nonzero torque, leading…
Shear-Driven Diffusion with Stochastic Resetting
Iman Abdoli, Kristian Stølevik Olsen, Hartmut Löwen
External flows, such as shear flow, add directional biases to particle motion, introducing anisotropic behavior into the system. Here, we explore the non-equilibrium dynamics that…
Tailoring the escape rate of a Brownian particle by combining a vortex flow with a magnetic field
Iman Abdoli, Hartmut Löwen, Jens-Uwe Sommer +1
The probability per unit time for a thermally activated Brownian particle to escape over a potential well is in general well-described by Kramers theory. Kramers showed that the es…
Collisions enhance self-diffusion in odd-diffusive systems
Erik Kalz, Hidde Derk Vuijk, Iman Abdoli +3
It is generally believed that collisions of particles reduce the self-diffusion coefficient. Here we show that in odd-diffusive systems, which are characterized by diffusion tensor…
Escape Dynamics in an Anisotropically Driven Brownian Magneto-System
Iman Abdoli, Jens-Uwe Sommer, Hartmut Löwen +1
Thermally activated escape of a Brownian particle over a potential barrier is well understood within Kramers theory. When subjected to an external magnetic field, the Lorentz force…
Brownian magneto-gyrator as a tunable microengine
Iman Abdoli, René Wittmann, Joseph Michael Brader +3
A Brownian particle performs gyrating motion around a potential energy minimum when subjected to thermal noises from two different heat baths. Here, we propose a magneto-gyrator ma…
Stochastic resetting of active Brownian particles with Lorentz force
Iman Abdoli, Abhinav Sharma
The equilibrium properties of a system of passive diffusing particles in an external magnetic field are unaffected by the Lorentz force. In contrast, active Brownian particles exhi…
Correlations in multithermostat Brownian systems with Lorentz force
Iman Abdoli, Erik Kalz, Hidde Derk Vuijk +4
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 th…
Unusual stationary state in Brownian systems with Lorentz force
Iman Abdoli, Hidde Derk Vuijk, Rene Wittmann +3
In systems with overdamped dynamics, the Lorentz force reduces the diffusivity of a Brownian particle in the plane perpendicular to the magnetic field. The anisotropy in diffusion…
Nondiffusive Fluxes in Brownian System with Lorentz Force
Iman Abdoli, Hidde Derk Vuijk, Jens-Uwe Sommer +2
The Fokker-Planck equation provides complete statistical description of a particle undergoing random motion in a solvent. In the presence of Lorentz force due to an external magnet…
