Abstract: Synchronization (self-organization in time) and swarming (self-organization in space) are universal phenomena that co-occur in many biological and physical systems. Swarmalators are entities that swarm through space and synchronize in time and are potentially considered to replicate the complex dynamics of many real-world systems. Prof. Ghosh will discuss minimal model of swarmalators that are solvable and give rich dynamics. Previously, the internal dynamics of swarmalators have been taken as a phase oscillator inspired by the Kuramoto model. Here, he will examine the internal dynamics utilizing an amplitude oscillator capable of exhibiting periodic and chaotic behaviors. He will discuss the effect of a predator-like agent in the swarmalators model. The collective behaviors of swarmalators with higher-order interactions will also be discussed.
