Universal mapping of topological singularities

Not Accessible

Your library or personal account may give you access

Abstract

We report universal mapping of topological Dirac-like points in momentum-space to optical vortices in real-space. This conversion persists even in stretched lattices, topologically protected by a quantized Berry phase.
