Abstract

ABDALLA, E.  and  BANERJEE, R.. Quantisation of the multidimensional rotor. Braz. J. Phys. [online]. 2001, vol.31, n.1, pp. 80-83. ISSN 1678-4448.  http://dx.doi.org/10.1590/S0103-97332001000100015.

We reconsider the problem of quantising a particle on the D-dimensional sphere. Adopting a Lagrangian method of reducing the degrees of freedom, the quantum Hamiltonian is found to be the usual Schrödinger operator without any curvature term. The equivalence with the Dirac Hamiltonian approach is demonstrated, either in the cartesian or in the curvilinear basis. We also briefly comment on the path integral approach.
