Universal conversion of topological singularities from momentum to real space

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate universal conversion of topological singularities in momentum-space (Dirac points) to topological defects in real-space (optical vortices). We show that this conversion persists even in stretched lattices, topologically protected by a quantized Berry phase.
