Asymmetry-controlled resonant transport in a Brownian flashing ratchet
Sudipta Mandal, Dipanjan Chakraborty, Debasish Chaudhuri
We investigate directed transport in a one-dimensional Brownian flashing ratchet with a piecewise-linear asymmetric periodic potential. Numerical solutions of the Fokker--Planck eq…

Independent Control of Transport and Order in a Ratcheted Colloidal Suspension
Sudipta Mandal, Dipanjan Chakraborty, Debasish Chaudhuri
We study directed transport in a two-dimensional suspension of repulsively interacting colloids driven by a stochastic asymmetric piecewise-linear flashing ratchet using large-scal…

Anisotropic active Brownian particle in two dimensions under stochastic resetting
Anirban Ghosh, Sudipta Mandal, Subhasish Chaki
We analytically investigate the dynamic behavior of an an-isotropic active Brownian particle under various stochastic resetting protocols in two dimensions. The motion of shape-asy…
