Title: pdf Author: Henrik Johannesson Created Date: 9/17/2014 5:03:18 PM 2020-03-19 · Download PDF Abstract: This Perspective examines the emerging applications of photonic topological insulators (PTIs) in the microwave domain. The introduction of topological protection of light has revolutionized the traditional perspective of wave propagation through the demonstration of backscatter-free waveguides in the presence of sharp bending and strong structural defects. The topological invariants of an interacting insulator can be calculated from Green’s function at zero-frequency. Nonzero frequencies can be safely ignored.

I will conclude by giving a conceptual description of topological insulators and mention some potential applications of such states.

The unique applicability of topological insulators to spintronic devices comes from the fact that the conducting electrons on the surface have no mass and are automatically “spin polarized,” leading to the unique half-integer quantum Hall effect that was observed in this research. 2020-07-20 This Perspective examines the emerging applications of photonic topological insulators (PTIs) in the microwave domain. The introduction of topological protection of light has revolutionized the traditional perspective of wave propagation through the demonstration of backscatter-free waveguides in the presence of sharp bending and strong structural defects.
