Scattering Dynamics and Boundary States of a Non-Hermitian Dirac Equation
Yun Yong Terh, Rimi Banerjee, Haoran Xue +1
We study a non-Hermitian variant of the (2+1)-dimensional Dirac wave equation, which hosts a real energy spectrum with pairwise-orthogonal eigenstates. In the spatially uniform cas…
Topological Transitions with an Imaginary Aubry-Andre-Harper Potential
Bofeng Zhu, Li-Jun Lang, Qiang Wang +2
We study one-dimensional lattices with imaginary-valued Aubry-Andre-Harper (AAH) potentials. Such lattices can host edge states with purely imaginary eigenenergies, which differ fr…
Anomalous Floquet non-Hermitian skin effect in a ring resonator lattice
He Gao, Haoran Xue, Zhongming Gu +6
We present a one-dimensional coupled ring resonator lattice exhibiting a variant of the non- Hermitian skin effect (NHSE) that we call the anomalous Floquet NHSE. Unlike existing a…
Amplification of quantum signals by the non-Hermitian skin effect
Qiang Wang, Changyan Zhu, You Wang +2
The non-Hermitian skin effect (NHSE) is a phenomenon whereby certain non-Hermitian lattice Hamiltonians, particularly those with nonreciprocal couplings, can host an extensive numb…
Roadmap on Topological Photonics
Hannah Price, Yidong Chong, Alexander Khanikaev +20
Topological photonics seeks to control the behaviour of the light through the design of protected topological modes in photonic structures. While this approach originated from stud…
Single-mode lasing based on PT-breaking of two-dimensional photonic higher-order topological insulator
B. F. Zhu, Q. Wang, Y. Q. Zeng +2
Topological lasers are a new class of lasers that seek to exploit the special properties of topological states of light. A typical limiting factor in their performance is the exist…
