Non-equilibrium physics inspired by biology: from fluctuating membranes to active gels
Nir Gov, (Weizmann Institute of Science)
The most ubiquitous and accessible non-equilibrium systems around us are in the form of living organisms. Motivated by pattern formation and random motion that are driven by active (out-of-equilibrium) processes in cells we investigate the similarities and differences between such motion and thermal random motion. A simple theoretical model of a kicked particle is used to extract analytic and numerical results which we then compare to observations of membrane fluctuations in cells, and fluctuations in active gels reconstituted in-vitro.
