Arbitrarily configurable nonlinear topological modes
Kai Bai, Jia-Zheng Li, Tian-Rui Liu +3
Topological modes (TMs) are typically localized at boundaries, interfaces and dislocations, and exponentially decay into the bulk of a large enough lattice. Recently, the non-Hermi…
A geometry-originated universal relation for arbitrary convex hard particles
Yuheng Yang, Duanduan Wan
We have discovered that two significant quantities within hard particle systems: the probability of successfully inserting an additional particle at random and the scale distributi…
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…
Effects of scars on crystalline shell stability under external pressure
Duanduan Wan, Mark J. Bowick, Rastko Sknepnek
We study how the stability of spherical crystalline shells under external pressure is influenced by the defect structure. In particular, we compare stability for shells with a mini…
