Rotating effects on an atom with a magnetic quadrupole moment confined to a quantum ring

We investigate rotating effects on an atom with a magnetic quadrupole moment that interacts with a radial electric field in a two-dimensional quantum ring through a single-particle approximation (V.F. Dmitriev et al., Phys. Rev. C 50, 2358 (1994)). We show that a Coulomb-type and a linear-type scalar potentials stem from the interaction between magnetic quadrupole moment and a radial electric field under rotating effects. Besides, we discuss the dependence of the angular frequency on the angular velocity of the rotating frame and the quantum numbers of the system.
