Superconducting transition temperatures of pure vanadium and vanadium-titanium alloys in the presence of dynamical electronic correlations

Autor: Jones, D., Östlin, A., Weh, A., Beiuseanu, F., Eckern, U., Vitos, L., Chioncel, L.

Publikováno v: Phys. Rev. B 109, 165107 (2024)

Ordinary superconductors are widely assumed insensitive to small concentrations of random nonmagnetic impurities, whereas strong disorder suppresses superconductivity, ultimately leading to a superconductor-insulator transition. In between these limi

Spectral properties of heterostructures containing half-metallic ferromagnets in the presence of local many-body correlations

Autor: A. Weh, J. Otsuki, H. Schnait, H. G. Evertz, U. Eckern, A. I. Lichtenstein, L. Chioncel

Publikováno v: Physical Review Research, Vol 2, Iss 4, p 043263 (2020)

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 of strong electronic correlations on the spectral properties (densit

Using wearable technology to objectively investigate physical behaviour and determine health outcomes of a physical activity intervention in patients with psoriasis

Autor: Rory Sheppard, Weh K. Gan, Gladys L. Onambele‐Pearson, Helen S. Young

Publikováno v: Skin Health and Disease, Vol 4, Iss 6, Pp n/a-n/a (2024)

Abstract Background Sedentary behaviour has a detrimental effect on health independent of the amount of physical activity undertaken. Despite the association of cardiometabolic and psychosocial comorbidities with psoriasis, how physical behaviour inf

Dynamical mean-field theory of the Anderson-Hubbard model with local and non-local disorder in tensor formulation

Autor: Weh, A., Zhang, Y., Östlin, A., Terletska, H., Bauernfeind, D., Tam, K. -M., Evertz, H. G., Byczuk, K., Vollhardt, D., Chioncel, L.

Publikováno v: Phys. Rev. B 104, 045127 (2021)

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 dynamical mean-field theory using tensor notation. The impurity model com

Spin-polarization and resonant states in electronic conduction through a correlated magnetic layer

Autor: Weh, Andreas, Appelt, Wilhelm H., Östlin, Andreas, Chioncel, Liviu, Eckern, Ulrich

The transmission through a magnetic layer of correlated electrons sandwiched between non-interacting normal-metal leads is studied within model calculations. We consider the linear regime in the framework of the Meir-Wingreen formalism, according to
