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.…
Dynamical density functional theory for dense odd-diffusive fluids
Iman Abdoli, René Wittmann, Hartmut Löwen
Odd diffusion breaks time-reversal symmetry in overdamped systems through transverse probability currents while preserving equilibrium steady states. In this work, we develop a dyn…
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.…
Confined active particles with spatially dependent Lorentz force: an odd twist to the "best Fokker-Planck approximation"
René Wittmann, Iman Abdoli, Abhinav Sharma +1
We derive a version of the so-called "best Fokker-Planck approximation" (BFPA) to describe the spatial properties of interacting active Ornstein-Uhlenbeck particles (AOUPs) in arbi…
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…
