A link between entropy production and topology

The Department Living Matter Physics from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) revealed a link between the generation of entropy and the topological features of a system. In their study, recently published in Nature Communications, the scientists investigated the random motion of particles in vortex flows. They found that fluctuations in entropy production can be characterized based only on the number of windings around the vortex, but not on the shape or size of the trajectory. These findings could contribute to a better understanding of microscopic systems, such as micro-motors or particles moving in biological media.
