DYNAMICS OF NONLINEAR AND QUANTUM SYSTEMS
Study the propagation of light through photonic crystals.
Apply mathematical methods to solve nonlinear equations describing the propagation of light in nonlinear media and also the Bose-Einstein condensates.
Combining these methods with numerical simulations developed by the group we have obtained new results on Bose-Einstein condensates and also interactions of emitters with photonic crystals.
