Title: Interactive active matter
Abstract: Active matter encompasses a wide range of systems that consist of individuals, which extract energy from their surroundings and convert it into mechanical work. Such individuals, including bacteria and eukaryotic cells, exist in extremely diverse environments, which, in turn, lead to a complex network of inter- and intra-population interactions. Mechanical forces, exerted and experienced by cells, can act as messengers, regulating individual behaviour, however, how they lead to emergent collective behaviours and the emergence of liquid crystalline features in such active systems have not been elucidated yet. Here, by utilising a suite of theoretical models at different scales, such as continuum liquid crystal theory and cell-based phase-field formulation, we investigate how mechanical interactions with surroundings and other cells can lead to collective cell migration.
