Goos-Hänchen shift at a temporal boundary

Abstract
While Goos--H\"anchen effects at spatial boundaries have been well studied, light-matter interactions at temporal boundaries have only recently become a subject of interest. Here, the authors develop a theory of time shifts for pulses reflected from a moving temporal boundary in a dispersive medium, and reveal the importance of the relative velocities of the pulse and boundary.
