We present an all-electron, periodic ${G}_{\text{0}}{W}_{\text{0}}$ implementation within the numerical atomic orbital (NAO) basis framework. A localized variant of resolution-of-the-identity (RI) approximation is employed to significantly reduce computational cost evaluating and storing two-electron Coulomb repulsion integrals. demonstrate that error arising from RI can be reduced insignifican...

Aim. To study the role of left atrial posterior wall (LAPW) isolation in increasing clinical efficacy radiofrequency ablation (RFA) patients with persistent fibrillation (PeAF) during electrophysiological studies. Methods. A single-center randomized prospective study. From February 2020 to 2021, 35 procedures were performed on PeAF. Patients into two groups - pulmonary vein (PVI) plus LAPW accordi...

Structural and electronic properties of the Sr2MnSbO6 perovskite in cubic (Fm-3m) tetragonal (I4m P/4mnc) crystallographic phases have been determined using Full Potential Linearized. Augmented Plane Waves (FP-LAPW) method, framework Density Functional Theory (DFT). The exchange correlation effects were treated Generalized Gradient. Approximation plus Hubbard term (GGA+U) approach, order to des...

This work focuses on study of the structural, electronic, thermodynamic and thermoelectric properties RbNbCd RbNbZn Half Heusler (HH), utilizing a full-potential linearized augmented plane wave (FP-LAPW) approach Boltzmann transport equation using constant relaxation time approximation within context density functional theory (DFT) as embedded in WIEN2k code. The structural analysis employed ge...
