Achieving Predictive Description of Negative Differential Resistance in Molecular Junctions Using a Range-Separated Hybrid Functional
(Wiley-VCH Verlag, 2021)Range-separated hybrid (RSH) functionals have been recently used to overcome the tendency of traditional density functional theory (DFT) calculations to overestimate the conductance of molecular junctions. Non-equilibrium ... -
Applicability of noninteger bessel type orbital basis sets: numerical and analytical approaches
(Springer Science and Business Media Deutschland GmbH, 2023)Recently, usefulness of the noninteger principal quantum numbers for Bessel type orbitals was discussed by Weniger in (Adv Quant Chem 83:209–237, 2021). In this study, we analyzed the applicability and numerical accuracy ... -
Application of quantum self-frictional nonperturbative theory for the study of atomic anharmonic oscillator potentials and their arbitrary derivatives
(Springer, 2021)The self-frictional (SF) nonperturbative theory, introduced by one of the authors, is used for the evaluation of the V-(pl*()) and V-(alpha*) atomic anharmonic oscillator potentials and their derivatives, where p(l)* = 2l ... -
Axial-vector nucleon-to-delta transition form factors using the complex-mass renormalization scheme
(American Physical Society, 2021)We investigate the axial-vector nucleon-to-delta transition form factors in the framework of relativistic baryon chiral perturbation theory at the one-loop order using the complex-mass renormalization scheme. We determine ... -
BVRI Photometric Observations, Light Curve Solutions and Orbital Period Analysis of BF Pav
