[Todos] HOY 14hs - Seminario: La fisica de Efimov

[Pablo Capuzzi]

Hola a todos,
        Les recuerdo del Seminario sobre "La fisica de Efimov: de 
nucleones a atomos"  por Alejandro Kievsky 
HOY a las 14hs en el Aula Federman del Departamento de Fisica. 
                        Saludos,
                                Pablo.

   TITLE: Efimov physics: from few nucleons to few atoms
   ABSTRACT:
   As V. Efimov showed in 1971, the large nucleon-nucleon
   scattering length has important implications in the
   structure of few-nucleon systems. This observation has been
   extended to analyze all systems having a large two-body
   scattering length with respect to the range of the interaction.
   A consequence of this fact is the appearance of an infinite
   spectrum in the three-body system presenting a discrete
   scaling of universal character. At present Efimov physics is
   intensively studied in trapped cold atoms. I will show some
   analogies between few-nucleon systems and few-atom systems and,
   using a new method of solving the Schoedinger equation, I will
   extract some universal relations in the spectra up to six bodies.
