A mathematical theory of in-​gap interface modes in photonic/phononic structures

Vortrag von Prof. Dr. Hai Zhang

Datum: 22.05.23  Zeit: 16.30 - 17.30  Raum: ETH HG E 23

The developments of topological insulators have provided a new avenue of creating interface modes (or edge modes) in photonic/phononic structures. Such created modes have a distinct property of being topologically protected and are stable with respect to perturbations in certain classes. In this talk, we will report recent results on the existence of in-​gap interface modes that are bifurcated from Dirac points in photonic/phononic structures. Both one-​dimensional and two-​dimensional structures will be discussed.
