Truncated unity functional renormalization group for multiband systems with spin-orbit coupling
G. A. H. Schober, J. Ehrlich, T. Reckling +1
Although the functional renormalization group (fRG) is by now a well-established method for investigating correlated electron systems, it is still undergoing significant technical…
Wavevector-dependent optical properties from wavevector-independent proper conductivity tensor
Ronald Starke, Giulio A. H. Schober, René Wirnata +1
We discuss the calculation of the refractive index by means of the ab initio scalar dielectric function and point out its inherent limitations. To overcome these, we start from the…
Why history matters: ab initio rederivation of Fresnel equations confirms microscopic theory of refractive index
R. Starke, G. A. H. Schober
We provide a systematic theoretical, experimental, and historical critique of the standard derivation of Fresnel's equations, which shows in particular that these well-established…
General form of the full electromagnetic Green function in materials physics
G. A. H. Schober, R. Starke
In this article, we present the general form of the full electromagnetic Green function which is suitable for the application in bulk materials physics. In particular, we show how…
Linear electromagnetic wave equations in materials
R. Starke, G. A. H. Schober
After a short review of microscopic electrodynamics in materials, we investigate the relation of the microscopic dielectric tensor to the current response tensor and to the full el…
Covariant Response Theory and the Boost Transform of the Dielectric Tensor
R. Starke, G. A. H. Schober
After a short critique of the Minkowski formulae for the electromagnetic constitutive laws in moving media, we argue that in actual fact the problem of Lorentz-covariant electromag…
