Observation of nonlinear higher-order topological insulators with unconventional boundary truncations
Changming Huang, Alexander V. Kireev, Yuxin Jiang +10
In higher-order topological insulators (HOTIs), topologically nontrivial phases are usually associated with the shift of Wannier centers to topologically nontrivial positions on th…
Observation of nonlinear topological corner states originating from different spectral charges
Victor O. Kompanets, Suge Feng, Yiqi Zhang +11
Higher-order topological insulators (HOTIs) are unique topological materials supporting edge states with the dimensionality at least by two lower than the dimensionality of the und…
Terahertz frequency conversion at plasma-induced time boundary
Yindong Huang, Bin Zhou, Aijun Xuan +8
We report on the frequency conversions of terahertz (THz) waves at ultrafast time boundaries created via femtosecond laser-induced air-to-plasma phase transitions. Our combined exp…
