Dr. Iñigo Liberal leads a research group at Public University of Navarre (UPNA), focused on extreme nanophotonic and quantum optical material. In 2022 he was awarded the Early Career Award from the journal Nanophotonics for his important contributions in the fields of near-zero index media (NZI) and quantum and thermal metamaterials.
Abstract
Time-varying media consists of materials or metamaterial constructs whose properties change in an ultra-fast manner, at time scales comparable to the frequency of operation. By breaking temporal symmetries, they enable light-matter interactions that cannot be observed in static (i.e., non-time-modulated) materials. In this talk, we will discuss the symmetries of time-varying media and how they lead to new opportunities in quantum and thermal light emission.
