Angular momentum projection integrals for coherent states
Serdar Kuyucak B, K. Unnikrishnan
Abstract
Angular momentum projection integrals arising from the coherent state representation of bosonic spectrum generating algebras are evaluated using analytical and algebraic methods. For the vibron model of diatomic molecules, a closed expression is derived by direct integration. For the general case, the integral is evaluated as a 1/N expansion by exploiting the symmetries of the underlying boson system and making use of computer algebra.
