Research Activities in the Department of Physics

The research activities in the Department of Physics revolve around two subthemes: Advanced Materials and computational sciences in the scope of science & Technology. Research interests of the Department also extend to the radiation physics field.

Advanced Materials

Advanced Materials research at the Department of Physics focuses on synthesizing and characterizing novel nano-materials and studying their influence on the properties of high-temperature superconductors (HTSCs). In addition, the Materials Science research group in the department has been studying a wide variety of the properties of a recently discovered HTSC known as an iron-based superconductor, which is expected to have wide applications in industry in addition to its great scientific interest.

Computational Sciences

Introduced a new approach in the perturbation theory (canonical functions) for the solution of the Schrödinger equation for the calculation of the vibrational energy levels for the ground and excited electronic states, the rotational and the centrifugal constants, the Franck-Condon factor and the matrix elements of molecules in the Raman and infrared transitions.

Determination, for the ground and excited states, the spectroscopic constants, rovibrational studies, the potential energy curves, the static and transition dipole moment, Franck-Condon factor, the radiation lifetime and the oscillator strength of the diatomic molecules.
