Active polymer translocation through flickering pores

ArXiv 1111.6498 (2011)

Authors:

Jack A Cohen, Abhishek Chaudhuri, Ramin Golestanian

Abstract:

Single file translocation of a homopolymer through an active channel under the presence of a driving force is studied using Langevin dynamics simulation. It is shown that a channel with sticky walls and oscillating width could lead to significantly more efficient translocation as compared to a static channel that has a width equal to the mean width of the oscillating pore. The gain in translocation exhibits a strong dependence on the stickiness of the pore, which could allow the polymer translocation process to be highly selective.

Relaxation in driven integer quantum Hall edge states

ArXiv 1111.3914 (2011)

Authors:

DL Kovrizhin, JT Chalker

Abstract:

A highly non-thermal electron distribution is generated when quantum Hall edge states originating from sources at different potentials meet at a quantum point contact. The relaxation of this distribution to a stationary form as a function of distance downstream from the contact has been observed in recent experiments [Phys. Rev. Lett. 105, 056803 (2010)]. Here we present an exact treatment of a minimal model for the system at filling factor 谓=2, with results that account well for the observations.
