# Scientific Work

## 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

_{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.
