Phononic Frequency Combs: Sound Waves Meet Quantum Precision

A quantum level quantum control of sound waves is achieved with the creation of phononic frequency combs. By means of nanomechanical resonators, I have seen how these devices may produce exactly spaced frequencies of sound, akin to optical frequency combs with light. New methods of quantum information processing and precise measurement depend on the capacity ...

Finding chronocrystals marks a remarkable advance in our knowledge of temporal symmetry in physical systems. By means of my studies on time crystals in quantum systems, I have found how these structures replicate their patterns in time instead of space, therefore challenging our accepted knowledge of equilibrium physics. Chronocrystals’ capacity to sustain constant motion without ...
