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…
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…
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…
Two step melting of the Weeks-Chandler-Anderson system in two dimensions
Shubhendu Shekhar Khali, Dipanjan Chakraborty, Debasish Chaudhuri
We present a detailed numerical simulation study of a two dimensional system of particles interacting via the Weeks-Chandler-Anderson potential, the repulsive part of the Lennard-J…
Persistence in Brownian motion of an ellipsoidal particle in two dimensions
Anirban Ghosh, Dipanjan Chakraborty
We investigate the persistence probability of the position of a Brownian particle with shape asymmetry in two dimensions. The persistence probability is defined as the proba…
Structure-dynamics relationship in ratcheted colloids: Resonance melting, dislocations, and defect clusters
Shubhendu Shekhar Khali, Dipanjan Chakraborty, Debasish Chaudhuri
We consider a two dimensional colloidal dispersion of soft-core particles driven by a one dimensional stochastic flashing ratchet that induces a time averaged directed particle cur…
