Carnegie Mellon University was awarded a $154,221 Project Grant from the National Science Foundation Division of Electrical, Communications and Cyber Systems under the Engineering program (CFDA 47.041) for the period of September 1, 2022 through August 31, 2025.
The award will support research to realize and investigate time crystals in non-isolated systems using photons in miniaturized nonlinear optical devices. Specifically, the awardee will demonstrate discrete time crystals in dissipative Kerr nonlinear cavities by leveraging nanofabrication of integrated photonic structures to realize time crystals in silicon nitride microring resonators pumped by polychromatic lasers. The state and phase transitions of the created time crystals will be controlled and tracked. The system is intended to allow for frequency reference transfer by locking pumps to external references. If successful, the research is expected to significantly advance investigation of time crystals as a new phase of matter and reveal practical applications by combining photonics and condensed matter physics concepts.
