Nonlinear dissipative coupled nanocavities

Contact: Alejandro GIACOMOTTI

Coupled nanocavities are basic building blocks for the implementation of fundamental physical phenomena leading to spatial and temporal complexity such as the spontaneous symmetry breaking [1]. The way is now open for the exploration of coherent optical excitation (resonant driving), mesoscopic assemblies or small ensembles, and nanocavity networks. A number of interesting nonlinear dissipative phenomena can be explored with these platforms such as Josephson vortex, far-from- equilibrium thermodynamics and classical phase transitions, parity-time symmetry breaking and so forth, which constitute the first axis of the project.
