Abstract

A new set of h(1)su(2) h(1) \oplus su(2) vector algebra eigenstates on the matrix domain is obtained by defining them as eigenstates of a generalized annihilation operator formed from a linear combination of the generators of this algebra which eigenvalues are distributed as the elements of a square complex normal matrix. A combined method is used to compute these eigenstates, namely, the method of exponential operators and that of a system of first-order linear differential equations. We compute these states for all possible combination of generators and classify them in different categories according to a generalized commutation relation as well as according to the value of a characteristic parameter related to the su(2)su(2) algebra eigenvalues. Proceeding in this way, we found a subset of generalized vector coherent states in the matrix domain which can be easily separated from the general set of Schr\"odinger-Robertson minimum uncertainty intelligent states. In particular, for a special choice of the matrix eigenvalue parameters we found the so-called vector coherent states with matrices associated to the Heisenberg-Weyl group as well as a generalized version of them, and also a direct connection with the coherent state quantization of quaternions.
