By applying properties of the
SU(2s+1) group, a spin coherent state based on arbitrary fiducial
vectors is constructed, taking as reference the cases proposed by
Matsumoto~\cite{matsumoto}. The path integral is obtained and using
the variational principle one find a system of equations that describe
the behavior of the Euler angles associated to the coherent state.
General expressions are found, likewise, for the dynamic and geometric
phases accumulated by the evolution of the state vector along cyclic
trajectories. A particle under pulsed magnetic field, and a Heisenberg
chain with periodic boundary conditions, are studied. |
