Abstract Symmetry considerations are taken into account when a particle in square well potential is studied. This system may display natural degeneracy, accidental degeneracy or systematic depending on the depth of potential. In order to obtain solutions associated with an arbitrary algebraic discrete variable representation approach based Pöschl-Teller functions proposed. It proved that geomet...

In this paper, the finite square well and its application are investigated, namely quantum state discrimination. The is treated in all standard textbooks on introductory mechanics. It used as a simple 'model of departure' many areas physics. atomic molecular physics, it may be model an electron moving mean field linear molecule also arises partial wave radial equation for spherically symmetric,...

The brief for this overview paper was to examine the possible impacts for children and youth exposed to international migration between developing countries. The overview of available data and research is exhaustive and well achieved in the paper. It would be hard to add to this overview, so this critique explores whether internal (within country) migration should be added to the brief. Then, I...

sometimes the need for non-circular ducts arises in many heat transfer applications because of lower pressure drop of non-circular cross section such as square duct compared to circular tube, particularly in compact heat. but square cross section has poor heat transfer performance and it is expected that using a nanofluid as a new heat transfer media may improve the heat transfer performance of...

Exact solvability of the discretized N−point version of the PT −symmetric squarewell model at all N is pointed out. Its wave functions are found proportional to the classical Tshebyshev polynomials Uk cos θ) of a complex argument. A compact secular equation is derived giving the real spectrum of energies at all the non-Hermiticity strengths Z ∈ (−Zcrit(N), Zcrit(N)). In the limit Z → 0 the mode...
