Time-varying media have recently emerged as a new paradigm for wave manipulation, due
to the synergy between the discovery of highly nonlinear materials, such as epsilon-near …

Recent progress in nanophotonics and material science has inspired a strong interest in
optically-induced material dynamics, opening new research directions in the distinct fields of …

Photonic time crystals (PTCs), materials with a dielectric permittivity that is modulated
periodically in time, offer new concepts in light manipulation. We study theoretically the …

Time reflection is a uniform inversion of the temporal evolution of a signal, which arises
when an abrupt change in the properties of the host material occurs uniformly in space. At …

Photonic Time-Crystals (PTCs) are materials in which the refractive index varies periodically
and abruptly in time. This medium exhibits unusual properties such as momentum bands …

We present an experimental study of optical time-refraction caused by time-interfaces as
short as a single optical cycle. Specifically, we study the propagation of a probe pulse …

In this opinion article, we briefly summarize some of the background materials and recent
developments in the field of temporal and spatiotemporal media and provide our opinion on …

We study light propagation in spatiotemporal photonic crystals: dielectric media that vary
periodically in both space and time. While photonic crystals (spatially periodic media) are …

Nonreciprocity is critically important in modern wave technologies, yet its general principles
and practical implementations continue to raise intense research interest, in particular in the …
