Variational Approach to the Dynamics of Bose-Einstein Condensates.I --Variational Ansatz and Quantum Dynamics--
Y. Tsue, D. Vautherin, T. Matsui
Variational method is applied to describe Bose-Einstein condensates (BEC) interacting via a pseudo-potential, taking into account quantum fluctuations around the mean field by the…
Variational calculations in gauge theories with approximate projection on gauge invariant states
C. Heineman, C. Martin, D. Vautherin +1
Variational calculations using Gaussian wave functionals combined with an approximate projection on gauge invariant states are presented. We find that the energy exhibits a minimum…
Temperature dependence of the response function of hot nuclear matter
Abdellatif Abada, Dominique Vautherin
The description of collective motion in nuclei at finite temperature using the framework of the random phase approximation is discussed. We focus on the special case of the isovect…
Two-Phonon States in Alkali-Metal Clusters
Abdellatif Abada, Dominique Vautherin
Two phonon-states of alkali-metal clusters (treated as jellium spheres) are calculated by using a method based on a perturbative construction of periodic orbits of the time-depende…
