Absolute negative mobility of an inertial Brownian particle in an oscillating potential

JC Wu, F Yang, TW Dong, M An - Physical Review E, 2024 - APS
Transport of an inertial Brownian particle in an oscillating potential is numerically
investigated in the presence of an external constant force. The oscillating potential can …

Simultaneous Control of Multispecies Particle Transport and Segregation in Driven Lattices

AK Mukhopadhyay, B Liebchen, P Schmelcher - Physical Review Letters, 2018 - APS
We provide a generic scheme to separate the particles of a mixture by their physical
properties like mass, friction, or size. The scheme employs a periodically shaken two …

Asymptotic population imbalance of an ultracold bosonic ensemble in a driven double well

J Chen, AK Mukhopadhyay, P Schmelcher - Physical Review A, 2020 - APS
We demonstrate that an ultracold many-body bosonic ensemble confined in a one-
dimensional double-well potential exhibits a population imbalance between the two wells at …

Spontaneous rectification and absolute negative mobility of inertial Brownian particles induced by Gaussian potentials in steady laminar flows

JC Wu, M An, WG Ma - Soft Matter, 2019 - pubs.rsc.org
We study the transport of inertial Brownian particles in steady laminar flows in the presence

Multiple current reversals using superimposed driven lattices

AK Mukhopadhyay, P Schmelcher - Applied Sciences, 2020 - mdpi.com
We demonstrate that directed transport of particles in a two dimensional driven lattice can be
dynamically reversed multiple times by superimposing additional spatially localized lattices …

Ratchet transport of overdamped particles in superimposed driven lattices

SN Huang, WJ Zhu, XQ Huang, BQ Ai, FG Li - Chinese Physics B, 2019 - iopscience.iop.org
Ratchet transport of overdamped particles is investigated in superimposed driven lattices
using Langevin dynamics simulations. It is found that noise can strongly affect the transport …

Controlling vortical motion of particles in two-dimensional driven superlattices

AK Mukhopadhyay, P Schmelcher - Physical Review B, 2020 - APS
We demonstrate the control of vortical motion of neutral classical particles in driven
