Isotopic spin and coherent states
K. -E. L. Eriksson, B.-S. Skagerstam · Journal of Physics A Mathematical and General · 1979
The authors review the concept of coherent states and extend the concept to a basis which transforms irreducibly under isotopic spin rotations. The construction is explicitly given for one-mode wavefunctions. The construction of a similar basis for fields can in principle be done by making use of the results in the present paper.
