    "abstract": "We show that for general deformations of SU(2) algebra, the dynamics in terms\nof ladder operators is preserved. This is done for a system of precessing\nmagnetic dipole in magnetic field, using the unitary phase operator which\narises in the polar decomposition of SU(2) operators. It is pointed out that\nthere is a single phase operator dynamics underlying the dynamics of usual and\ndeformed ladder operators.",
