Absolute negative mobility of an active tracer in a crowded environment
Pierre Rizkallah, Alessandro Sarracino, Olivier Bénichou +1
Absolute negative mobility (ANM) refers to the situation where the average velocity of a driven tracer is opposite to the direction of the driving force. This effect was evidenced…
Superionic liquids in conducting nanoslits: A variety of phase transitions and ensuing charging behavior
Maxym Dudka, Svyatoslav Kondrat, Olivier Bénichou +2
We develop a theory of charge storage in ultra-narrow slit-like pores of nano\-structured electrodes. Our analysis is based on the Blume-Capel model in external field, which we sol…
Contact Kinetics in Fractal Macromolecules
Maxim Dolgushev, Thomas Guérin, Alexander Blumen +2
We consider the kinetics of first contact between two monomers of the same macromolecule. Relying on a fractal description of the macromolecule, we develop an analytical method to…
Geometric friction directs cell migration
M. Le Berre, Yan-Jun Liu, J. Hu +5
In the absence of environmental cues, a migrating cell performs an isotropic random motion. Recently, the breaking of this isotropy has been observed when cells move in the presenc…
Molecular diffusion between walls with adsorption and desorption
Maximilien Levesque, Olivier Bénichou, Benjamin Rotenberg
The time dependency of the diffusion coefficient of particles in porous media is an efficient probe of their geometry. The analysis of this quantity, measured e.g. by nuclear magne…
Searching fast for a target on a DNA without falling to traps
O. Bénichou, Y. Kafri, M. Sheinman +1
Genomic expression depends critically both on the ability of regulatory proteins to locate specific target sites on a DNA within seconds and on the formation of long lived (many mi…
