- Spontaneous synchronization: from fireflies to Schmidt-Higgs mode in Superconductors
- Time: 10:00 am - 6:00 pm
- Place: 5310 Chamberlin
- Speaker: Maxim Dzero , Kent State University
- Abstract: The tendency to synchronize is one of the most ubiquitous and at the same time mysterious drive in all of nature. In the introductory part of my talk, I will show how the study of synchrony could deepen our understanding of not only certain aspects enormous congregations of fireflies blinking on and off in complete unison, but also the collectively synchronous behavior of 10^23 electrons in superconductors. In the main part of my talk, I will discuss an example of spontaneous synchronization in superconductors which are driven out of equilibrium by a sudden perturbation. The particular focus of my talk will be on collective excitation of the amplitude (Schmidt-Higgs) mode and how the dynamics of this mode changes in the presence of disorder. Finally, I will discuss how the phenomenon of spontaneous synchronization in conventional superconductors can be probed experimentally.
