Comparison between effective Hamiltonians in symmetry restoring theories: Intrinsic excitations in superfluid nuclei

  • 1. Department of Physics, University of La Plata, 1900 La Plata, Argentina (Argentina)

Description

The comparison between effective Hamiltonians, constructed within the framework of symmetry restoring methods, is discussed for the case of intrinsic two-quasiparticle excitations in superfluid nuclei. Particularly, the meaning of currently adopted approximations, i.e., number symmetry restoring effective interactions and ideal quasiparticle representation in gauge space, is discussed in connection with an intrinsic symmetry breaking mechanism in the number variable
