On-chip Amorphous THz Topological Photonic Interconnects
Rimi Banerjee, Abhishek Kumar, Thomas Tan Caiwei +6
Valley Hall photonic crystals (VPCs) offer the potential to create topological waveguides capable of guiding light through sharp bends on a chip. They can seamlessly integrate with…
Localization of chiral edge states by the non-Hermitian skin effect
Gui-Geng Liu, Subhaskar Mandal, Peiheng Zhou +11
Quantum Hall systems host chiral edge states extending along the one-dimensional boundary of any two-dimensional sample. In solid state materials, the edge states serve as perfectl…
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…
