Nearest-Neighbor Tight-Binding Realization of Hyperbolic Lattices with Gauge Structures
Xianghong Kong, Xingsi Liu, Shuihua Yang +4
A systematic framework for realizing gauge extensions of hyperbolic lattices within the nearest-neighbor tight-binding formalism is developed. Using the triangle gro…
One-way heat transfer in deep-subwavelength thermophotonics
Shuihua Yang, Chen Jianfeng, Guoqiang Xu +3
Nonreciprocal thermophotonics, by breaking Lorentz reciprocity, exceeds current theoretical efficiency limits, unlocking opportunities to energy devices and thermal management. How…
Engineering Moiré Meta-crystals with Conventional Photonic and Phononic Structures
Mourad Oudich, Xianghong Kong, Tan Zhang +2
Recent discoveries on Mott insulating and unconventional superconducting states in twisted bilayer graphene with Moiré superlattices have reshaped the landscape of ''twistronics''…
Realizing topologically protected ghost surface polaritons by lattice transformation optics
Xianghong Kong, Chuanjie Hu, Xingsi Liu +4
While conventional surface waves propagate along the surface and decay perpendicularly from the interface, the ghost surface polaritons show oblique propagation direction with resp…
