Effective Action for a Statistical System with a Field dependent Wave Function
Pierre Gosselin, Herve Mohrbach, Alain Berard
We compute the first order correction in to the field dependent wave function in Statistical Field Theory. These corrections are evaluated by several usual methods. We lim…
Angular Symmetry Breaking Induced by Electromagnetic Field
A. Berard, J. Lages, H. Mohrbach
It is well known that velocities does not commute in presence of an electromagnetic field. This property implies that angular algebra symmetries, such as the sO(3) and Lorentz alge…
Monopole and Berry Phase in Momentum Space in Noncommutative Quantum Mechanics
Alain Berard, Herve Mohrbach
To build genuine generators of the rotations group in noncommutative quantum mechanics, we show that it is necessary to extend the noncommutative parameter to a field operator,…
Probing the shell valence structure underlying the B(E2: 0+->2+) for N,Z~40: preponderance of the p-n interaction over the sub-shell closures
Isabelle Deloncle, Brigitte Roussiere
The very simple product of the number of particles by the number of holes appearing in the expression of the reduced B(E2:0+->2+) transition probability of even-even nuclei obtaine…
L'argument Einstein Podolsky Rosen (EPR) : Paradoxe, Alternative, Demonstration
Pierre Roussel
The EPR (Einstein, Podolsky, Rosen) argument and the Schrodinger cat paradox are revisited in relation with modern quantum optics and atomic physics and with the concept of decoher…
Bound state equation in the Wilson loop approach with minimal surfaces
F. Jugeau, H. Sazdjian
The large-distance dynamics in quarkonium systems is investigated, in the large N limit, through the saturation of Wilson loop averages by minimal surfaces. Using a representation…
