However, because of the connection with the nuclear shell model, the dependence of the energies and interactions on the number of valence neutrons and protons is known

It turns out that the three- site four-spin interaction 5' affects largely the Curie temperature T,, and that the effect of J' on Tc is large for the

The interest of the bidimensional equivalent of this model has recently been renewed with the study of graphene where this condition is sometimes called “infinite mass condition”,

Physics is richer when the Efimov effect [11] sets in: the continuous scaling invariance is broken, there appears a length scale R t characterizing the interaction, the three-

The simplest description of three-body losses is the model of Braaten and Hammer, where three incoming low-energy unbound atoms are reflected back as three unbound atoms with

All kinds of ions can be trapped simultaneously and since parametric resonances are proportional to the square root of the charge/mass ratio the EIBT can be used as a mass

Moreover, in the zero range model, there are energy crossings between universal and efimovian states as a function of R t /a ho (see solid lines in Fig.2a); as we shall see, for
