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…
Initial-Value Problem for Inhomogeneous Condensate: Gaussian Approximation and Beyond
Chi-Yong Lin, A. F. R. de Toledo Piza
Using many-body theory we develop a set of formally exact kinetic equations for inhomogeneous condensate and one-body observables. The method is illutrated for phi^4 field theory i…
Elementary Excitations of a Relativistic Scalar Plasma System
E. R. Takano Natti, Chi-Yong Lin, A. F. R. de Toledo Piza +1
We investigate the physics of elementary excitations for the so called relativistic scalar plasma system. Following the standard many-body procedure we have obtained the RPA equati…
