Elasticity typically refers to a material's ability to store energy, whereas viscosity refers to a
material's tendency to dissipate it. In this review, we discuss fluids and solids for which this is …

In active matter systems, individual constituents convert energy into non-conservative forces
or motion at the microscale, leading to morphological features and transport properties that …

Out of equilibrium, a lack of reciprocity is the rule rather than the exception. Non-reciprocity
occurs, for instance, in active matter,,,,–, non-equilibrium systems,–, networks of neurons …

Active particles that are self-propelled by converting energy into mechanical motion
represent an expanding research realm in physics and chemistry. For micrometer-sized …

Differently from passive Brownian particles, active particles, also known as self-propelled
Brownian particles or microswimmers and nanoswimmers, are capable of taking up energy …

We examine a nonreciprocally coupled dynamical model of a mixture of two diffusing
species. We demonstrate that nonreciprocity, which is encoded in the model via antagonistic …

The motion of self-propelled massive particles through a gaseous medium is dominated by
inertial effects. Examples include vibrated granulates, activated complex plasmas and flying …

We study the thermodynamic properties induced by non-reciprocal interactions between
stochastic degrees of freedom in time-and space-continuous systems. We show that, under …

We theoretically study mixtures of chemically interacting particles, which produce or
consume a chemical to which they are attracted or repelled, in the most general case of …

We study a two-dimensional, nonreciprocal XY model, where each spin interacts only with
its nearest neighbors in a certain angle around its current orientation, ie, its “vision cone.” …
