Mahmoud EL Korek is a full professor at the Physics Department of Beirut Arab University. Dr. Mahmoud received his M.Sc. and Ph.D. degree from University Claude Bernard–Lyon I, France. His doctoral thesis work on the theoretical calculation of the problem of the vibrational and rotational motion of the diatomic molecule by introducing the canonical functions approach. From 1987-1993 he joined the American University of Beirut and worked on the dipole moment and matrix elements calculations where he received in 1990 the Research Award in Natural Sciences from the American University of Beirut. In 1994 Dr Korek joined Beirut Arab University and supervised a research group in molecular physics. He received grants from Cedre project (Collaboration between Lebanon and France) and from CNRS-L (The National Council for Scientific Research). His research interests cover the field of the electronic structure, the problem of vibration-rotation, and the dipole moment calculation of diatomic molecule. He has published over 121 papers in the field, two books, with the contribution with large number of conferences and the supervision of more than 89 master and PhD thesis.
In my research work, I 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. Researches on ultracold molecules and Bose-Einstein condensate materials are of a current and great challenge in the spectroscopic studies because of their importance in the cooling and trapping of atoms and molecules, their role in high precision spectroscopy and Bose-Einstein condensation (BEC). They may also allow for the study of collective quantum effects in molecular systems. After the success in laser cooling in 1997 I started in collaboration with the Laboratory of Ionic and Molecular Spectroscopy in Claude Bernard University Lyon I France (LASIM) a project of theoretical studies on a series of diatomic molecules and molecular ions for the 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 studied molecules.
