Effects of non-Hermitian perturbations on Weyl Hamiltonians with arbitrary topological charges
Alexander Cerjan, Meng Xiao, Luqi Yuan +1
We provide a systematic study of non-Hermitian topologically charged systems. Starting from a Hermitian Hamiltonian supporting Weyl points with arbitrary topological charge, adding…
A Photonic Crystal Slab Laplace Differentiator
Cheng Guo, Meng Xiao, Momchil Minkov +2
We introduce an implementation of a Laplace differentiator based on a photonic crystal slab that operates at transmission mode. We show that the Laplace differentiator can be imple…
Enhanced High-Harmonic Generation from an All-Dielectric Metasurface
Hanzhe Liu, Cheng Guo, Giulio Vampa +7
The recent observation of high-harmonic generation from solids creates a new possibility for engineering fundamental strong-field processes by patterning the solid target with subw…
Synthetic space with arbitrary dimensions in a few rings undergoing dynamic modulation
Luqi Yuan, Meng Xiao, Qian Lin +1
We show that a single ring resonator undergoing dynamic modulation can be used to create a synthetic space with an arbitrary dimension. In such a system the phases of the modulatio…
Creating anyons from photons using a nonlinear resonator lattice subject to dynamic modulation
Luqi Yuan, Meng Xiao, Shanshan Xu +1
We study a one-dimensional photonic resonator lattice with Kerr nonlinearity under the dynamic modulation. With an appropriate choice of the modulation frequency and phase, we find…
Topologically Charged Nodal Surface
Meng Xiao, Shanhui Fan
We report the existence of topologically charged nodal surface, a band degeneracy on a two-dimensional surface in momentum space that is topologically charged. We develop a Hamilto…
