Effective Quantum Theories for Transport in Inhomogeneous Systems with Non-trivial Band Structure
Christian Wickles, Wolfgang Belzig
Starting from a general -band Hamiltonian with weak spatial and temporal variations, we derive a low energy effective theory for transport within one or several overlapping band…
Reflectionless Transport of Surface Dirac Fermions on Topological Insulators with Induced Ferromagnetic Domain Walls
Christian Wickles, Wolfgang Belzig
The properties of surface Dirac Fermions on a 3D topological insulator in proximity to a magnetic insulator with spatially textured magnetization are considered. We present an exac…
Electronic transport in ferromagnetic conductors with inhomogeneous magnetic order parameter -- domain-wall resistance
Christian Wickles, Wolfgang Belzig
We microscopically derive transport equations for the conduction electrons in ferromagnetic materials with an inhomogeneous magnetization profile. Our quantum kinetic approach incl…
Thermal breakdown of coherent backscattering: a case study of quantum duality
Christian Wickles, Cord Mueller
We investigate coherent backscattering of light by two harmonically trapped atoms in the light of quantitative quantum duality. Including recoil and Doppler shift close to an optic…
