Swarmalators with thermal noise

We investigate a population of swarmalators, mobile versions of phase oscillators that both sync in time and swarm through space. We focus on an XY-type model of identical swarmalators running on a one-dimensional ring and subject to thermal noise. We uncover four distinct collective states, some of...

Summary:We investigate a population of swarmalators, mobile versions of phase oscillators that both sync in time and swarm through space. We focus on an XY-type model of identical swarmalators running on a one-dimensional ring and subject to thermal noise. We uncover four distinct collective states, some of which capture the behavior of real-world swarmalators such as vinegar eels and sperm. Among these, the most intriguing is the “mixed state,” which blends two of the other states. We present a comprehensive phase diagram from the Fourier mode analysis with a high accuracy, which is in excellent agreement with numerical simulation results. Our model serves as a tractable toy model for thermal systems that both self-synchronize and self-assemble interdependently.
