Boundary effects produced by a Chern-Simons (CS) extension to electrodynamics are analyzed exploiting the Green's function (GF) method. We consider the electromagnetic field coupled to a. term in a way that has been proposed to provide the correct low-energy effective action for topological insul...

Green's function approach to Chern-Simons extended electrodynamics: An effective theory describing topological insulators
The Green's function method is used to analyze the boundary effects produced by a Chern-Simons extension to electrodynamics. We consider the electromagnetic field coupled to a theta term that is piecewise constant in different regions of space, separated by a common interface Sigma, the theta bou...

Electro- and magnetostatics of topological insulators as modeled by planar, spherical, and cylindrical θ boundaries: Green’s function approach
In the last couple of decades the Standard Model Extension has emerged as a fruitful framework to analyze the empirical and theoretical extent of the validity of cornerstones of modern particle physics, namely, of Special Relativity and of the discrete symmetries C, P and T (or some combinations ...
