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…
How reciprocity impacts ordering and phase separation in active nematics?
Arpan Sinha, Debasish Chaudhuri
Active nematics undergo spontaneous symmetry breaking and show phase separation instability. Within the prevailing notion that macroscopic properties depend only on symmetries and…
Active stop and go motion: a strategy to improve spatial exploration and survival
Fernando Peruani, Debasish Chaudhuri
We consider active Brownian particles that intermittently switch between active and inactive states. Such behavior is ubiquitous at all scales, from bacteria to animals and in arti…
Cooperation and competition in the collective drive by motor proteins: Mean active force, fluctuations, and self-load
Chitrak Karan, Debasish Chaudhuri
We consider the dynamics of a bio-filament under the collective drive of motor proteins. They are attached irreversibly to a substrate and undergo stochastic attachment-detachment…
Extension and dynamical phases in random walkers depositing and following chemical trails
Subhashree Subhrasmita Khuntia, Abhishek Chaudhuri, Debasish Chaudhuri
Active walker models have proved to be extremely effective in understanding the evolution of a large class of systems in biology like ant trail formation and pedestrian trails. We…
