The group of Prof. Shimshon Barad is conducting experimental research in several sub-fields of modern optics, including nonlinear optics, quantum optics, and ultrafast optical spectroscopy. At present the research in nonlinear optics focuses on the fluid-like propagation of light in self-defocusing nonlinear media, and the possibility of using this analogy to hydrodynamics to construct an all-optical analog event horizon and demonstrate analogs of Hawking radiation.
This research is carried out in collaboration with the theory group of Prof. Victor Fleurov. The research in quantum optics, carried out in collaboration with the theory group of Prof. Lev Vaidman, involves weak measurements that demonstrate "which path" paradoxes in nested interferometers. The optically-induced insulator-metal phase transition in vanadium oxide is studied in collaboration with the group of Prof. Ivan K. Schuller at the Department of Physics at the University of California, San Diego.
