Topological Space‐Time Photonic Transitions in Angular‐Momentum‐Biased Metasurfaces
Advanced Optical Materials, 2020In this paper, topological space‐time photonic transition of light in angular‐momentum‐biased metasurfaces is established, which yields a superposition of orbital‐angular‐momentum (OAM)‐carrying beams at distinct frequency harmonics upon scattering whose

On β*-supra topological spaces
Journal of Discrete Mathematical Sciences & Cryptography, 2023In this paper, a new type of supra closed sets is introduced which we called supra β*-closed sets in a supra topological space. A new set of separation axioms is defined, and its many properties are examined. The relationships between supra β*-Ti –spaces

Nature Photonics, 2014
Applying the mathematical concept of topology to the wave-vector space of photonics yields exciting opportunities for creating new states of light with useful properties such as unidirectional propagation and the ability to flow around imperfections. The

Experimental observation of non-Abelian topological acoustic semimetals and their phase transitions
Nature Physics, 2021Topological phases of matter connect mathematical principles to real materials, and may shape future electronic and quantum technologies. So far, this discipline has mostly focused on single-gap topology described by topological invariants such as Chern ...

Observation of a phononic quadrupole topological insulator
Nature, 2017The modern theory of charge polarization in solids is based on a generalization of Berry’s phase. The possibility of the quantization of this phase arising from parallel transport in momentum space is essential to our understanding of systems with ...
