The effect of structural relaxations on the magnetocrystalline anisotropy energy (MAE) was investigated by using density functional theory (DFT). impact magnetostructural coupling MAE discussed, including effects attempt frequency. for ferromagnetic FePt (3.45 meV/formula unit) and antiferromagnetic PtMn (0.41 were calculated within local approximation (LDA). relaxation found to give a <0.5%...

In the approximate call-strings-based context-sensitive static analysis, because the number of distinguished contexts is finite, multiple call-contexts are inevitably joined at the entry of a procedure and the output at the exit is propagated to multiple returnsites. We found that these multiple returns frequently create a single large cycle (we call it “butterfly cycle”) covering almost all pa...

In this paper, the quasi static-approximation on hydrodynamics of compact objects is proposed in $f(R, T)$ gravity, where $R$ scalar curvature and $T$ trace stress-energy tensor, by exploring axial reflection symmetric space time stuffed with anisotropic dissipative matter contents. The set invariant-velocities defined to comprehend concept static-approximation. As a consequence, evolution show...

Based on the path integral approach the partition function of a many body system with separable two body interaction is calculated in the sense of a semiclassical approximation. The commonly used Gaussian type of approximation, known as the perturbed static path approximation (PSPA), breaks down near a crossover temperature due to instabilities of the classical mean field solution. It is shown ...
