Superconducting transition temperatures of pure vanadium and vanadium-titanium alloys in the presence of dynamical electronic correlations
D. Jones, A. Östlin, A. Weh +4
Ordinary superconductors are widely assumed insensitive to small concentrations of random nonmagnetic impurities, whereas strong disorder suppresses superconductivity, ultimately l…

Dynamical mean-field theory of the Anderson-Hubbard model with local and non-local disorder in tensor formulation
A. Weh, Y. Zhang, A. Östlin +7
To explore correlated electrons in the presence of local and non-local disorder, the Blackman-Esterling-Berk method for averaging over off-diagonal disorder is implemented into dyn…

Spectral properties of heterostructures containing half-metallic ferromagnets in the presence of local many-body correlations
A. Weh, J. Otsuki, H. Schnait +4
In this work, we investigate models for bulk, bi- and multilayers containing half-metallic ferromagnets (HMFs), at zero and at finite temperature, in order to elucidate the effects…
