(World Scientific Publishing Company, 2018-12-17)The effect of nitrogen doping on the structural, electronic and optical properties of hexagonal and cubic Ge2Sb2Te5 (GST) has been investigated from first principles. The nitrogen content was set to 10 at.% and 25 at.%, ... -
Analytical Absorption Cross-Section for Photon by a Hydrogen 2s Atom
(IOP Publishing, 2011-04)We calculate the absorption cross-section for photon by a hydrogen 2s atom using the quantum-classical approximation for the total photo cross-section of many electron atoms. With the application of the first-order term ... -
Ultracold Atom-Ion Systems in Hybrid Traps
(Humboldt-Universität zu Berlin, 2017-11-21)This thesis deals with the theoretical description of a hybrid system of an ultracold neutral atom and a single ion. These hybrid atom-ion systems combine the key advantages of ultracold neutral atoms and ions. In particular, ... -
Symmetry Dependent Analytical Pseudopotential for Helium Atom
(2019-11-11)Electron-electron interaction is the origin of the many-body problems usually encountered in physics and chemistry. Helium atom and other two-electron systems are the simplest many-body systems in nature. The Schr¨odinger ... -
Multipole expansion of integral powers of cosine theta
(Nature Publishing Group, 2020-11-18)Legendre polynomials form the basis for multipole expansion of spatially varying functions. The technique allows for decomposition of the function into two separate parts with one depending on the radial coordinates only ... -
