Observation of full momentum bandgap in photonic time crystals
Bolun Huang, Zebin Zhu, Genrong Yu +1
The hallmark feature of photonic time crystals (PTCs) is the momentum bandgap, yet opening such a gap is extremely challenging, as it demands strong and rapid temporal modulation o…

Spatiotemporal topological phase transitions in photonic spacetime crystals
Zebin Zhu, Bolun Huang, Siqi Xu +5
Topological phase transitions have played a central role in topological physics. However, such transitions have so far been restricted to spatial or temporal crystals. Here, we tra…
