We study an energy-dependent potential related to the Rosen-Morse potential. We give in closed-form the expression of a system of eigenfunctions of the Schrodinger operator in terms of a class of functions associated to a ...

The concept of security is very important for the economic and social development for any region, state or country. In particular, the concept of energy security is now more important due to the negative effects of climate ...

We present a new method to construct the exactly solvable PT-symmetric potentials within the framework of the position-dependent effective mass Dirac equation with the vector potential coupling scheme in 1 + 1 dimensions. ...

We argue that the pseudoharmonic potential provides an unsuitable description of the interatomic potential-energy function of a diatomic molecule because of its wrong behaviour at origin and infinity and because it does ...

The present work approaches the necessity of the hydraulic and energetic efficiency indicator development for the management and decision making of water supply systems (WSSs) that can enable the comparison between the ...

In this work we investigate possible approximations to the free energy and chemical potential of water within a Newton black film as a natural nanoconfinement. As a first step we explore the different approximations in a ...
