Fermion Hamiltonians with Monopole and Quadrupole Pairing

摘要

Shell model Hamiltonians which have a set of eigenstates made up of only monopole and quadrupole pairs are presented. These Hamiltonians have many other types of states as well. The subspace of states made up of monopole and quadrupole pairs have a one-to-one correspondence to states made up of monopole and quadrupole bosons. Some properties of these Hamiltonians are discussed. 6 references. (ERA citation 04:031780)
