Résumé |
Effective field Theory (EFT) has become the standard protocol in the treatment of the nucleon-nucleon interaction. In this talk I will show some recent progress that we have made in a direction that slightly differs from the
standard use of chiral-EFT to produce potentials employed in few- or many-
body calculations. Starting from the EFT Lagrangian, and passing through the
Schroedinger representation, it is possible to reshape the theory in terms of
non-relativistic nucleons coupled to relativistic dynamical pions that occupy
momentum-labelled modes in a finite periodic box. We then managed to set
up an efficient Quantum Monte Carlo framework to make use of this formulation[1]. Some results on the properties of a single nucleon and of the deuteron will be shown.
