Diffusion of Chiral Janus Particles in a Sinusoidal Channel
Xue Ao, Pulak Kumar Ghosh, Yunyun Li +3
We investigate the transport diffusivity of artificial microswimmers, a.k.a. Janus particles, moving in a sinusoidal channel in the absence of external biases. Their diffusion cons…
Ising Metamagnet Driven by Propagating Magnetic Field Wave: Nonequilibrium Phases and Transitions
Muktish Acharyya
The nonequilibrium responses of Ising metamagnet (layered antiferromagnet) to the propagating magnetic wave are studied by Monte Carlo simulation. Here, the spatio-temporal variati…
Active Brownian motion in a narrow channel
Xue Ao, Pulak Kumar Ghosh, Yunyun Li +3
We review recent advances in rectification control of artificial microswimmers, also known as Janus particles, diffusing along narrow, periodically corrugated channels. The swimmer…
Chimera states in a population of identical oscillators under planar cross-coupling
C. R. Hens, A. Mishra, P. K. Roy +2
We report the existence of a chimera state in an assembly of identical nonlinear oscillators that are globally linked to each other in a simple planar cross-coupled form. The rotat…
Escape Kinetics of Self-Propelled Janus Particles from a Cavity: Numerical Simulations
Pulak Kumar Ghosh
We numerically investigate the escape kinetics of elliptic Janus particles from narrow two-dimensional cavities with reflecting walls. The self-propulsion velocity of the Janus par…
Cold gas in group-dominant elliptical galaxies
E. O'Sullivan, F. Combes, S. Hamer +3
We present IRAM 30m telescope observations of the CO(1-0) and (2-1) lines in a sample of 11 group-dominant elliptical galaxies selected from the CLoGS nearby groups sample. Our obs…
