Collective Excitation of a Hybrid Atomic/Molecular Bose Einstein Condensate
Chi-Yong Lin, M. S. Hussein, A. F. R. de Toledo Piza +1
The collective excitation of hybrid atomic-molecular condensate are studied using variational method. The dipole response of the system is studied in detail. We found that the out-…

Giant Resonances in Coulomb Excitations of Relativistic Ions
M. S. Hussein, A. F. R. de Toledo Piza, O. K. Vorov
We propose a soluble model to incorporate the nonlinear effects in the transition probabilities of the multiphonon Giant Dipole Resonances based on the SU(1,1) algebra. Analytical…

Distribution of matrix elements of random operators
M. S. Hussein, M. P. Pato
It is shown that an operator can be defined in the abstract space of random matrices ensembles whose matrix elements statistical distribution simulates the behavior of the distribu…
