Topological photonics by breaking the degeneracy of line node singularities in semimetal-like photonic crystals
Steffen Börm, Fatemeh Davoodi, Ralf Köhl +1
Degeneracy is an omnipresent phenomenon in various physical systems, which has its roots in the preservation of geometrical symmetry. In electronic and photonic crystal systems, ve…

Distributed -matrices for boundary element methods
Steffen Börm
Standard discretization techniques for boundary integral equations, e.g., the Galerkin boundary element method, lead to large densely populated matrices that require fast and effic…
