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…
