In systems possessing spatial or dynamical symmetry breaking, Brownian motion combined
with unbiased external input signals, deterministic and random alike, can assist directed …

The interior of a living cell is a crowded, heterogenuous, fluctuating environment. Hence, a
major challenge in modeling intracellular transport is to analyze stochastic processes within …

One of the major challenges in modern biology is to understand how the molecular
components of a living cell operate in a highly noisy environment. What are the specific …

We demonstrate the equilibration of isolated macroscopic quantum systems, prepared in
nonequilibrium mixed states with a significant population of many energy levels, and …

Diffusive transport of particles or, more generally, small objects, is a ubiquitous feature of
physical and chemical reaction systems. In configurations containing confining walls or …

Single molecule methods have provided a significantly new look at the behavior of
biomolecules in both equilibrium and non-equilibrium conditions. Most notable are the …

We report experimentally the dynamic properties of the entry and transport of unfolded and
native proteins through a solid-state nanopore as a function of applied voltage, and we …

In the absence of advection, confined diffusion characterizes transport in many natural and
artificial devices, such as ionic channels, zeolites, and nanopores. While extensive …

In the scenario of the narrow escape problem (NEP) a particle diffuses in a finite container
and eventually leaves it through a small'escape window'in the otherwise impermeable …

One of the recent frontiers of nanotechnology research involves machines that operate at
nano-and microscales, also known as nano/micromotors. Their potential applications in …
