On-Chip Optical Skyrmionic Beam Generators
Wenbo Lin, Yasutomo Ota, Yasuhiko Arakawa +1
Optical skyrmion beams, which encompass two-dimensional topology in their spatial structures, are promising for ultra-dense optical communications and advanced matter manipulation.…
Space-Time Hopfion Crystals
Wenbo Lin, Nilo Mata-Cervera, Yasutomo Ota +2
Hopfions, higher-dimensional topological quasiparticles with sophisticated 3D knotted spin textures discovered in condensed matter and photonic systems, show promise in high-densit…
Topological Corner States in Bilayer and Trilayer Systems with Vertically Stacked Topological Heterostructures
Natsuko Ishida, Motohiko Ezawa, Guangtai Lu +4
We investigate bilayer and trilayer systems composed of topologically distinct, vertically stacked layers, forming topological heterostructures based on the Benalcazar-Bernevig-Hug…
Topological Laser in Anomalous Quadrupole Topological Phases
