30BB03 Physics Seminar Room

Staff, Students

Speaker:

Alejandro Kievsky, INFN Pisa

 I will review some issues in the theoretical description of few-nucleon systems using realistic nucleon-nucleon  potentials. I will discuss some open problems, as for  example the Ay puzzle, and the effects of the three-nucleon  force. At the end of the talk I will connect the few-nucleon spectrum to the Efimov physics. As V. Efimov showed in 1971, the large nucleon-nucleon scattering length has important  implications in the structure of few-nucleon systems. 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.
