Ratchet effects can arise for single or collectively interacting Brownian particles on an
asymmetric substrate when a net dc transport is produced by an externally applied ac …

Geometric frustration and the ice rule are two concepts that are intimately connected and
widespread across condensed matter. The first refers to the inability of a system to satisfy …

We develop a general framework to describe the thermodynamics of microscopic heat
engines driven by arbitrary periodic temperature variations and modulations of a mechanical …

This article reviews recent research on the collective dynamical behavior of colloids with
dipolar or multipolar interactions. Indeed, whereas equilibrium structures and static self …

A Brownian particle moving in the vicinity of a generic potential minimum under the influence
of dissipation and thermal noise from two different heat baths is shown to act as a minimal …

Microbot propulsion has seen increasing interest in recent years as artificial methods that
overcome the well-established reversible and challenging nature of microscale fluid …

There are many examples of driven and active matter systems containing particles that
exhibit circular motion with different chiralities, such as swimming bacteria near surfaces or …

Topological protection allows robust transport of localized phenomena such as quantum
information, solitons and dislocations. The transport can be either dissipative or non …

Electrochemically fabricated magnetic mesoporous CoNi@ Pt nanorods are excellent
nanomotors with controlled magnetic propulsion and excellent catalytic properties. The core …

A platform of discrete microscopic magnetic elements patterned on a surface offers dynamic
control over the motion of fluid-borne cells by reprogramming the magnetization within the …
