Title: Dynamics of swarmalators

Speaker: Dibakar Ghosh, Associate Professor, Physics and Applied Mathematics Unit, Indian Statistical Institute, Kolkata, India.

Swarmalators are entities with the simultaneous presence of swarming and synchronization that reveal emergent collective behavior due to the fascinating bidirectional interplay between phase and spatial dynamics. Although different coupling topologies have already been considered, recently we introduce time-varying competitive phase interaction among swarmalators where the underlying connectivity for attractive and repulsive coupling varies depending on the vision (sensing) radius. In this talk, we will discuss some systematic approaches and review the collective dynamics of swarmalators analytically and/or numerically. Some of the states (the phase wave and split phase wave) resemble those seen in systems of Janus matchsticks or Japanese tree frogs. The others (such as the sync and unsteady states) may be observable in systems of vinegar eels, electrorotated Quincke rollers, or other swarmalators moving in disordered environments. Long-term states of position aggregation and phase synchronization will be discussed with some future problems.
