Cargo Towing by Artificial Swimmers
Debajyoti Debnath, Pulak K. Ghosh, Yunyun Li +2
An active swimmer can tow a passive cargo by binding it to form a self-propelling dimer. The orientation of the cargo relative to the axis of the active dimer's head is determined…
Temperature dependence of thermal conductivities of coupled rotator lattice and the momentum diffusion in standard map
Yunyun Li, Nianbei Li, Baowen Li
In contrary to other 1D momentum-conserving lattices such as the Fermi-Pasta-Ulam (FPU-) lattice, the 1D coupled rotator lattice is a notable exception which conserves total…
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…
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…
1D momentum-conserving systems: the conundrum of anomalous versus normal heat transport
Yunyun Li, Sha Liu, Nianbei Li +2
Transport and diffusion of heat in one dimensional (1D) nonlinear systems which {\it conserve momentum} is typically thought to proceed anomalously. Notable exceptions, however, ex…
Noisy saltatory spike propagation: The breakdown of signal transmission due to channel noise
Yunyun Li, Gerhard Schmid, Peter Hanggi
Noisy saltatory spike propagation along myelinated axons is studied within a stochastic Hodgkin-Huxley model. The intrinsic noise (whose strength is inverse proportional to the nod…
