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 with improved energy functionals in gauge theories
C. Heinemann, E. Iancu, C. Martin +1
For a SU(N) Yang-Mills theory, we present variational calculations using gaussian wave functionals combined with an approximate projection on gauge invariant states. The projection…
The transition temperature of the dilute interacting Bose gas for internal degrees of freedom
Gordon Baym, Jean-Paul Blaizot, Jean Zinn-Justin
We calculate explicitly the variation of the Bose-Einstein condensation temperature induced by weak repulsive two-body interactions to leading order in the interaction…
The transition temperature of the dilute interacting Bose gas
Gordon Baym, Jean-Paul Blaizot, Markus Holzmann +2
We show that the critical temperature of a uniform dilute Bose gas must increase linearly with the s-wave scattering length describing the repulsion between the particles. Because…
Neutrino propagation and spin zero sound in hot neutron matter with Skyrme interactions
J. Navarro, E. S. Hernandez, D. Vautherin
We present microscopic calculations of neutrino propagation in hot neutron matter above nuclear density within the framework of the Random Phase Approximation . Calculations are pe…
Quantum generalization of the classical rotating solutions of the O(N) model
D. Vautherin, T. Matsui
Analytic solutions of the mean field evolution equations for an N-component scalar field with O(N) symmetry are presented. These solutions correspond to rotations in isospin space.…
