Role of topological defects in the two-stage melting and elastic behavior of active Brownian particles
Year: 2020
Type: article
Abstract: This work investigates the non-equilibrium phase transitions in dense states of active Brownian particles . The authors study the role of topological defects, as described by the Kosterlitz-Thouless-Halperin-Nelson-Young theory of two-dimensional melting for systems in equilibrium, in phase transitions of active systems. A comparison of the defect structures and elastic constants with respect to those in equilibrium systems is performed which reveals the possibility of a significantly different mechanism at play at such a high degree of activity.
