Extension of the Barut–Girardello coherent state and path integral
Kazuyuki Fujii, Kunio Funahashi
We extend the Barut–Girardello coherent state for the representation of SU(1,1) to the coherent state for a representation of U(N,1) and construct the measure. We also construct a path integral formula for some Hamiltonian.
