Geometry-induced superdiffusion in driven crowded systems
Olivier Bénichou, Anna Bodrova, Dipanjan Chakraborty +5
Recent Molecular Dynamics simulations of glass-forming liquids revealed superdiffusive fluctuations associated with the position of a tracer particle (TP) driven by an external for…
Trajectory-to-trajectory fluctuations in first-passage phenomena in bounded domains
T. G. Mattos, C. Mejía-Monasterio, R. Metzler +2
We study the statistics of the first passage of a random walker to absorbing subsets of the boundary of compact domains in different spatial dimensions. We describe a novel diagnos…
Fluctuations and correlations of a driven tracer in a hard-core lattice gas
O. Bénichou, P. Illien, G. Oshanin +1
We consider a driven tracer particle (TP) in a bath of hard-core particles undergoing continuous exchanges with a reservoir. We develop an analytical framework which allows us to g…
Optimal least-squares estimators of the diffusion constant from a single Brownian trajectory
Denis Boyer, David S. Dean, Carlos Mejía-Monasterio +1
Modern developments in microscopy and image processing are revolutionising areas of physics, chemistry, and biology as nanoscale objects can be tracked with unprecedented accuracy.…
Active transport in dense diffusive single-file systems
P. Illien, O. Bénichou, C. Mejía-Monasterio +2
We study a minimal model of active transport in crowded single-file environments which generalises the emblematic model of single file diffusion to the case when the tracer particl…
On the non-equivalence of two standard random walks
O. Benichou, K. Lindenberg, G. Oshanin
We focus on two models of nearest-neighbour random walks on d-dimensional regular hyper-cubic lattices that are usually assumed to be identical - the discrete-time Polya walk, in w…
