Field of Research

Condensed Matter Theory, in particular new and functional quantum systems, strongly correlated electron systems, and light-matter interaction: application to superconductivity as well as collaboration with experimentalists.

1. Novel Josephson effect in superconducting nanostructures

Prediction of a novel class of Josephson effects in Triplet-superconductor – Ferromagnet – Triplet-superconductor (TFT) junctions, in particular: prediction of

(a)   a spin Josephson effect without global phase difference,

(b)   existence of a macroscopic spin current, and

(c)   realization of a superconducting qubit.

Furthermore, investigation of 0-p transitions (switching properties) as well as realization of new functional interfaces.

Method used:
semiclassical theory employing the Bogoliubov-de Gennes approach and Eilenberger equations.

2. Response and transport in unconventional superconductors

Derivation of the electronic Raman response function for metals with anisotropic relaxation rates and generalization of the Lindhard function due to collision effects. Further generalization to the pair-breaking Raman effect in non-centrosymmetric superconductors revealing simultaneously singlet- and triplet-pairing due to strong anisotropic spin-orbit coupling. Formulation and classi­fication of transport equations for generalized external perturbations resulting in characteristic response functions, respectively.

Method used:
kinetic and generalized response theory

3. Elementary excitations in high-T_c superconductors

Calculation and analysis of self-energy effects in high-T_c cuprates, in particular comparing with experiments concerning the 'kink' (observed by ARPES) and 'resonance peak' (measured by INS experiments) and their anisotropy in momentum space (Raman scattering). Formulation of a microscopic theory for Cooper-pairing due to spin fluctuations yielding a superconducting d_x2-y2-wave order parameter. Contrasting these results with LDA-based calculations for the phonon-induced (a) self-energy effects and (b) pairing interaction. Analysis of the in-plane anisotropy in connection with an s-wave admixture to the superconducting gap.
