A Cornell-led team used ultrafast laser spectroscopy to scrutinize a key intermediate state during singlet fission and found that in certain molecules the intermediate can be directly generated with a strikingly simple technique.

With pulses of sound through tiny speakers, Cornell physics researchers have clarified the basic nature of the newly discovered superconductor uranium ditelluride.

Karan Mehta, assistant professor of electrical and computer engineering in Cornell Engineering, is one of six Cornell researchers who recently received National Science Foundation Faculty Early Career Development Awards. Mehta’s award supports his group’s investigations of ion-light interaction in tailored spatial field profiles, in which fine spatial variations of the field profile can potentially enhance basic operations relevant for quantum computation and atomic clocks.
