Spin-dependent gain and loss in photonic quantum spin Hall systems
Tian-Rui Liu, Kai Bai, Jia-Zheng Li +3
Topological phases are greatly enriched by including non-Hermiticity. While most works focus on the topology of the eigenvalues and eigenstates, how topologically nontrivial non-He…
Chiral photonic crystals from sphere packing
Tao Liu, Ho-Kei Chan, Duanduan Wan
Inspired by recent developments in self-assembled chiral nanostructures, we have explored the possibility of using spherical particles packed in cylinders as building blocks for ch…
Effects of orientational and positional randomness of particles on photonic band gap
Zichen Qin, Tao Liu, Duanduan Wan
A recent work [PRL, 126, 208002 (2021)] has explored how thermal noise-induced randomness in a self-assembled photonic crystal affects photonic band gaps (PBGs). For the system of…
The suppression of Finite Size Effect within a Few Lattices
Tao Liu, Kai Bai, Yicheng Zhang +4
Boundary modes localized on the boundaries of a finite-size lattice experience a finite size effect (FSE) that could result in unwanted couplings, crosstalks and formation of gaps…
