Soft topological objects in topological media
Abstract
Topological invariants in terms of the Green's function in momentum and real space determine properties of smooth textures within topological media. In space dimension d = 1 the topological invariant N 3 in terms of the Green's function [InlineMediaObject not available: see fulltext.](ω, k x , x) determines the fermion number of the kink, while in space dimension d = 3 the topological invariant N 5 in terms of the Green's function [InlineMediaObject not available: see fulltext.](ω, k x , k y , k z , z) determines quantization of Hall conductivity in the soliton plane within the topological insulators.
