Graph-informed simulation-based inference for models of active matter. (arXiv:2304.06806v1 [cond-mat.soft])
cs.LG updates on arXiv.org arxiv.org
Many collective systems exist in nature far from equilibrium, ranging from
cellular sheets up to flocks of birds. These systems reflect a form of active
matter, whereby individual material components have internal energy. Under
specific parameter regimes, these active systems undergo phase transitions
whereby small fluctuations of single components can lead to global changes to
the rheology of the system. Simulations and methods from statistical physics
are typically used to understand and predict these phase transitions for
real-world observations. In …
