Pranešimo tema: Three- and four-body scattering: from nuclear reactions to cold atoms
Three- and four-body scattering is described in the framework of Faddeev-type integral equations that are solved numerically using momentum-space partial-wave representation. The Coulomb interaction between charged particles is included using the screening and renormalization method. The technique is applied to three-nucleon hadronic and electromagnetic reactions and to four-nucleon elastic, transfer, charge-exchange, and breakup reactions. Furthermore, the method has been applied successfully to elastic, transfer, and breakup reactions in three-body-like nuclear systems. Examples are deuteron scattering on stable nuclei and proton scattering on weakly bound two-body systems such as one-neutron halo nuclei. Finally, the technique has been extended to study the four-boson universal/Efimov physics that may be realized in the systems of ultracold atoms near Feshbach resonance.
