Nonconimutative quantum mechanics

Gamboa J.; Loewe, M.; Rojas J.C.


A general noncommutative quantum mechanical system in a central potential V= V(r) in two dimensions is considered. The spectrum is bounded from below and, for large values of the anticommutative parameter ?, we find an explicit expression for the eigenvalues. In fact, any quantum mechanical system with these characteristics is equivalent to a commutative one in such a way that the interaction V(r) is replaced by V = V(? HO,L? z), where ? Ho is the Hamiltonian of the two-dimensional harmonic oscillator and L? z is the z component of the angular momentum. For other finite values of ? the model can be solved by using perturbation theory. © 2001 The American Physical Society.
