Title: Time-varying Media and Their Symmetries
When: Tuesday, April 02, 2024, 12:00
Place: Department of Theoretical Condensed Matter Physics, Faculty of Sciences, Module 5, Seminar Room (5th Floor)
Speaker: Iñigo Liberal, Universidad Pública de Navarra, Spain.
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.
