متن کاملOrigin of chaos in the spherical nuclear shell model: role of symmetries
To elucidate the mechanism by which chaos is generated in the shell model, we compare three random–matrix ensembles: the Gaussian orthogonal ensemble, French’s two–body embedded ensemble, and the two–body random ensemble (TBRE) of the shell model. Of these, the last two take account of the two–body nature of the residual interaction, and only the last, of the existence of conserved quantum numb...
متن کاملThe spherical collapse model with shell crossing
In this work, we study the formation and evolution of dark matter halos by means of the spherical infall model with shell-crossing. We present a framework to tackle this effect properly, that does not involve the adiabatic approximation, and is based on the numerical follow-up, with time, of that individual shell of matter that contains always the same fraction of mass with respect to the total...
متن کاملSymmetries in Connection Preserving Deformations
We wish to show that the root lattice of Bäcklund transformations of the qanalogue of the third and fourth Painlevé equations, which is of type (A2 +A1) , may be expressed as a quotient of the lattice of connection preserving deformations. Furthermore, we will show various directions in the lattice of connection preserving deformations present equivalent evolution equations under suitable trans...
متن کاملStatistical properties and broken symmetries within the shell model
Shell-model calculations in the s-d shell have been utilized to examine how the statistical behavior of eigenvalues and reduced transition probabilities are affected by broken isospin symmetry. Calculations have been performed for the nuclides 22Na, 26Al, and 34Cl and have been compared to existing experimental data for 26Al and 30P. The eigenvalue statistics depend on the magnitude of the Coul...
