In the past ten years, the ideas of supersymmetry have been profitably applied to many
nonrelativistic quantum mechanical problems. In particular, there is now a much deeper …

Some selected topics on the subject of large-N expansions are reviewed here. A brief
discussion of large-N critical phenomena is also presented. Generalizing the Schrödinger …

In this study, the Schrödinger equation (SE) with screened Kratzer potential (SKP) in the
presence of external magnetic and AB-flux fields is investigated using the factorization …

Higher dimensional theories have attracted much attention because they make it possible to
reduce much of physics in a concise, elegant fashion that unifies the two great theories of …

A detailed study of the bound-state properties of the Hulthén potential is presented. Accurate
eigenenergies are obtained for the Hulthén potential by numerical integration of the …

We show that an excellent analytic approximation to the energy eigenvalues and
eigenfunctions of the Schrödinger equation can be obtained using the shifted 1 N …

The magnetization and magnetic susceptibility of GaAs/AlGaAs quantum ring (QR) with the
presence of Rashba spin-orbit interaction and acceptor Gaussian impurity have been …

The bottomonium spectrum is far from being established. The structures of higher vector
states, including the ϒ (10580), ϒ (10860), and ϒ (11020) states, are still in dispute. In …

In Gödel-type Som–Raychaudhuri (SR) cosmic string spacetime background, we revisit
Klein–Gordon (KG) oscillators and report their exact solutions for positive/negative vorticity …

The investigation ofmost problems of quantum physics leads to the solution of the
Schrodinger equation with an appropriate interaction Hamiltonian or potential. However, the …
