Energy transfer in small nano-sized systems can be very different from that in their
macroscopic counterparts due to reduced dimensionality, interaction with surfaces, disorder …

The directional motion of micro-and nanoparticles can be induced not only directly due to
the effect of forces with a nonzero average value, which set the direction of the motion, but …

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

This work focuses on the dynamics of particles in a confined geometry with position-
dependent diffusivity, where the confinement is modelled by a periodic channel consisting of …

Stochastic perturbations and periodic excitations are generally regarded as sources to
induce critical transitions in complex systems. However, we find that they are also able to …

A prerequisite for isolating diseased cells requires a mechanism for effective mass-based
separation. This objective, however, is generally rather challenging because typically no …

We investigate the directional locking effects that arise when a monolayer of paramagnetic
colloidal particles is driven across a triangular lattice of magnetic bubbles. We use an …

Absolute negative mobility (ANM) in nonequilibrium systems depicts the possibility of
particles propagating toward the opposite direction of an external force. We uncover in this …

We study different types of microswimmers moving in channels with varying cross section
and thereby interacting hydrodynamically with the channel walls. Starting from the …

Spontaneous segregation of run-and-tumble particles with different velocities in
microchannels is investigated by numerical simulations. Self-propelled particles are known …
