Light-front time picture of the Bethe-Salpeter equation
Tobias Frederico, J. H. O. Sales, B. V. Carlson +1
We show the light-front representation of the field theoretical Bethe-Salpeter equation (BSE) in the ladder approximation using the quasi potential reduction. We discuss the equiva…

Liquid-Gas phase transition in Bose-Einstein Condensates
A. Gammal, T. Frederico, L. Tomio +1
We study the effects of a repulsive three-body interaction on a system of trapped ultra-cold atoms in a Bose-Einstein condensed state. The corresponding wave non-linear Schrödi…

How reliable is the mean-field Nuclear Matter description for supporting Chiral Effective Lagrangians?
A. Delfino, M. Malheiro, T. Frederico
The link between non-linear chiral effective Lagrangians and the Walecka model description of bulk nuclear matter [1] is questioned. This fact is by itself due to the Mean Field Ap…
