Chemists Work ‘In Between’ Light, Matter and Imaginary Cat to Improve Technology
University of California San Diego’s Wei Xiong studies the science of “in between.” Specifically, the physical chemist studies mixed states of light and matter in order to better understand how the two forms of energy interact and communicate. Xiong does this by mixing light and matter to create hybrid quantum combinations whose properties he and his team measure and analyze. Recent research by Xiong; Bo Xiang, a Ph.D. candidate in his group; and postdoctoral scholar Raphael Ribeiro, from the Joel Yuen-Zhou Group, was published by Proceedings of the National Academy of Sciences (PNAS) in an article titled, “Two-dimensional infrared (2D IR) spectroscopy of vibrational polaritons.”
