Moving Through Disorder: Collective Trapping, Collective Escaping and Sub-diffusion

Explore a 54-minute seminar lecture examining the movement dynamics of biological entities in heterogeneous environments, delivered by Professor Fernando Peruani from CY Cergy Paris University. Delve into the fundamental differences between transport properties in heterogeneous versus homogeneous media, with particular focus on phenomena such as spontaneous particle trapping and sub-diffusion. Learn about the impossibility of long-range order in two-dimensional polar active liquids within heterogeneous environments, and understand how equations of motion with Hamiltonian structure prevent particle trapping while those with attractors lead to bounded trajectories. Examine cutting-edge research findings supported by multiple published works in Physical Review Letters and Communications Physics, offering insights into the mathematical modeling of movement in disordered environments applicable to various scales of biological systems, from cellular to vertebrate levels.
