Acoustic dip in the effective temperature of hot Brownian motion
Mayank Srivastava, Dipanjan Chakraborty
A hot Brownian particle is driven by thermal fluctuations from a nonuniformly heated solvent and therefore obeys a fluctuation-dissipation relation with a frequency-dependent effec…
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…
Effect of inertia on the evasion and pursuit dynamics of prey swarms and the emergence of an optimal mass ratio for the predator-prey arms race
Dipanjan Chakraborty, Arkayan Laha, Rumi De
We show, based on a theoretical model, how inertia plays a pivotal role in the survival dynamics of a prey swarm while chased by a predator. With the varying mass of the prey and p…
Persistence of an active asymmetric rigid Brownian particle in two dimensions
Anirban Ghosh, Sudipta Mandal, Dipanjan Chakraborty
We have studied the persistence probability of an active Brownian particle with shape asymmetry in two dimensions. The persistence probability is defined as the the probabil…
Coarse Graining Nonisothermal Microswimmer Suspensions
Sven Auschra, Dipanjan Chakraborty, Gianmaria Falasco +2
We investigate coarse-grained models of suspended self-thermophoretic microswimmers. Upon heating, the Janus spheres, with hemispheres made of different materials, induce a heterog…
