|Abstract:||The spin 1 particle is treated in the presence of the Dirac magnetic monopole in the Minkowski and Lobachevsky spaces. Separating the variables in the frame of the matrix 10-component Duﬃn–Kemer–Petiau approach and making a nonrelativistic approximation in the corresponding radial equations, a system of three coupled second order linear diﬀerential equations is derived for each type of geometry. For the Minkowski space, the nonrelativistic equations are disconnected using a linear transformation, which makes the mixing matrix a diagonal one. The resultant three unconnected equations involve three roots of a cubic algebraic equation as parameters. The approach allows extension to the case of additional external spherically symmetric ﬁelds. The Coulomb potential is considered and three series of energy spectra are derived. Special attention is given to the states with minimum value of the total angular momentum. In the case of the curved background of the Lobachevsky geometry, the mentioned linear transformation does not disconnect the nonrelativistic equations in the presence of the monopole. Nevertheless, we derive the solution of the problem in the case of minimum total angular momentum and in presence of the Coulomb ﬁeld. Finally, considering the case without the monopole ﬁeld, we show that for Coulomb potential the problem is reduced to a system of three diﬀerential equations involving a hypergeometric and two general Heun equations. Imposing on the parameters of the latter equations a speciﬁc requirement, reasonable from the physical standpoint, we derive the corresponding energy spectra.|
