The interaction between light and the time-varying medium exhibits non-Hermitian characteristics, leading to intriguing phenomena, such as parametric amplification, momentum gaps, and temporal refraction. In this study, we introduce the concept of the conformally evolved spatiotemporal modulation, w...
