Twist-Induced Hyperbolic Shear Metasurfaces
Simon Yves, Emanuele Galiffi, Xiang Ni +2
Following the discovery of moiré-driven superconductivity in twisted graphene multilayers, twistronics has spurred a surge of interest in tailored broken symmetries through angular…
Demonstration of acoustic high-order Stiefel-Whitney semimetal in bilayer graphene sonic crystals
Xiao Xiang, Xiang Ni, Feng Gao +4
Recently, higher-order topological phases have endowed materials many exotic topological phases. For three-dimensional (3D) higher-order topologies, it hosts topologically protecte…
Topological Metamaterials
Xiang Ni, Simon Yves, Alex Krasnok +1
One of the most significant breakthroughs in physics of the last decade has been the discovery that materials with non-trivial topological properties for electronic, electromagneti…
Layer-Resolved Resonance Intensity of Evanescent Polariton Modes in Anisotropic Multilayers
Nikolai Christian Passler, Giulia Carini, Dmitry N. Chigrin +1
Phonon polariton modes in layered anisotropic heterostructures are a key building block for modern nanophotonic technologies. The light-matter interaction for evanescent excitation…
Fourth-Order Topological Insulator via Dimensional Reduction
Kai Chen, Matthew Weiner, Mengyao Li +3
The properties of topological systems are inherently tied to their dimensionality. Higher-dimensional physical systems exhibit topological properties not shared by their lower dime…
Direct visualization of topological transitions and higher-order topological states in photonic metasurfaces
Anton Vakulenko, Svetlana Kiriushechkina, Mengyao Li +6
Topological photonic systems represent a new class of optical materials supporting boundary modes with unique properties, not found in conventional photonics. While the early resea…
