Special Issue : "Recent Advances in Applications of Potential Models to Study Physical Systems"

Brief Overview of the Special Issue

Quantum mechanics (QM) is a wide field that has attracted the attention of physicists, chemists, engineers, and mathematicians alike since its invention more than ten decades ago by the German theoretical physicist, Max Karl Ernst Ludwig Planck.  QM is the basic concept that can efficiently demystify the dynamics of a particle in the micro-physical terrain. Actually, it possesses the mathematical underpinning that gives profound comprehension into the physics of solids, semiconductor and superconductor devices, plasmas, lasers and so on. It incorporates all modern physics disciplines like condensed matter, molecular, atomic, nuclear and particle physics, optics, thermodynamics, statistical physics, etc.

To this end, to carry out studies and applications in quantum mechanics, potential models are employed. Potential models are at the very core of quantum mechanics and physics at large. Strictly speaking, potentials are carefully worked-out demonstration of influences which confine particles of a system in a specific region. Interatomic potentials are mathematical expressions for computing the potential energy of a system of atoms with given position in space. Interatomic potentials are extensively used as the physical basis of molecular dynamics simulations in computational chemistry, computational physics and computational materials science, both to predict quantitative materials properties and qualitative trends.

Potentials have many forms depending upon the interaction of particles within the system such as harmonic oscillator, Coulomb potential, Kratzer potential, screened potential, Deng–Fan potential, etc. and some combinations of these potentials and a lot of research work has been carried out to solve several wave equations (relativistic and non-relativistic), exactly or approximately, for such interactions.

The failure of the harmonic oscillator to describe interatomic interactions in diatomic molecules led to the discovery of the Morse potential. The success of this model need not be overemphasized. Several instances have inspired researchers to propose improved interaction model, e.g. when there was a loophole in the description of the James Chadwick’s atomic model, Hideki Yukawa proposed the screened coulomb potential which includes an exponentially decay term  and an electromagnetic term. The Hellmann potential which is a combination of the well-known Coulomb potential and the Yukawa (screened Coulomb) potential was proposed by Han Hellman. This model was used as an approximation for the simplified description of complex systems. This potential arose in an attempt to replace the tedious effects of the motion of the core (i.e. non-valence) electrons of an atom and its nucleus with an effective potential. 

However, it behoves every physicist and related experts to continuously seek for a better molecular or interaction potential that simulates quasi-perfectly the interactions in a physical system. Several applications of potential models to predict thermodynamic properties, behavior of molecules, etc. with high accuracy have been witnessed for some time now.

Therefore we invite researchers to submit original research articles and reviews to this Special Issue of the Journal of the Nigerian Society of Physical Sciences (JNSPS) on “Recent Advances in Applications of Potential Models to Study Physical Systems” that aims to identify and review the latest research in this research direction that have demonstrated to have a great impact in the field.
