Randomness and Emerging Order in Nuclear Structure

In order to investigate to what extent is the low-lying behavior of even-even nuclei dependent on particular nucleon-nucleon interactions, we consider systems of bosons where these interactions are taken as gaussian random numbers with equal likelyhood of being attractive or repulsive. We find a statistical dominance of L = 0 ground states and other correlations, which we analyze in terms of a mean field approach. Para investigar hasta que punto el comportamiento de los núcleos está determinado por interacciones particulares entre los nucleones, consideramos sistemas de bosones con interacciones gaussianas aleatorias, donde dichas interacciones tienen la misma probabilidad de ser atractivas o repulsivas. Encontramos un dominio estad́ıstico de estados base L = 0 y otras correlaciones, que analizamos en términos de un método de campo medio. PACS numbers: 05.30.Jp, 21.60.Ev, 21.60.Fw, 24.60.Lz
