The electronic, magnetic, and transport properties of Fe-intercalated 2H-TaS2 have been investigated by means of the Korringa-Kohn-Rostoker (KKR) method. The nonstoichiometry and disorder in the system have been accounted for using the coherent potential approximation (CPA) alloy theory. A pronounced influence of disorder on the spin magnetic moment has been found for the ferromagnetically orde...

We describe an ab initio theory of finite temperature magnetism in strongly-correlated electron systems. The formalism is based on spin density functional theory, with a self-interaction corrected local spin density approximation (SIC-LSDA). The self-interaction correction is implemented locally, within the KKR multiplescattering method. Thermally induced magnetic fluctuations are treated using...

Using the Korringa-Kohn-Rostoker coherent-potential approximation in the atomic-sphere approximation (KKR-ASA CPA) we have studied the changes in the electronic structure and the superconducting transition temperature Tc in Nb1−xB2 alloys as a function of x. We find that the variation in the electronic structure of Nb1−xB2 alloys as a function of x is consistent with the rigid-band model. Howev...

The ever increasing availability of supercomputing resources led computer-based materials science into a new era high-throughput calculations. Recently, Pizzi et al. [Comp. Mat. Sci. 111, 218 (2016)] introduced the AiiDA framework that provides way to automate calculations while allowing store full provenance complex workflows in database. We present development AiiDA-KKR plugin allows perform ...

Sequential Bayesian filters in non-linear dynamic systems require the recursive estimation of predictive and posterior probability density function (pdf). This paper introduces a filter called adaptive kernel Kalman (AKKF). The AKKF approximates arbitrary pdf hidden states using mean embedding (KME) reproducing Hilbert space (RKHS). In parallel with KME, some particles data are used to capture ...
