A system kept out of equilibrium in the stationary state by the external source of energy stores an energy in excess over its value at equilibrium. We determine this excess energy, $U$ for two model systems: the ideal gas and the Lennard-Jones liquid. We show that in order to describe non-equilibirum states an external energy source must be explicitly included in the analysis. The final...

Spatially Correlated Noise (SCN) emerges in various physical systems, e.g. plasma dynamics, ensembles of active particles and in the self-assembly phenomena. SCN-driven dynamics resembles also the dynamic heterogeneity, i.e. the coexistence of domains with highly correlated mobility, which emerge in the glass transition. In this talk the multi-particle collective dynamics of particles driven...

We study theoretically a possible physical mechanism for formation of multicellular protrusions in carcinoma at the onset of metastasis. We suggest it might be a consequence of a very simple physical instability resulting from coupling between cell velocity and direction of active traction. It is reminiscent of the classical viscous fingering instability. We use it to show that, for a...
