We show the existence ofa phase transition at b=O in an ensemble of non-interacting one-dimensional anharmonic oscillators each moving under the influence of the potential V(X) =a.?( It bx\*/Za)'. This is a consequence of the abrupt change in the nature of the energy eigenvalue spectrum of each osci

The connected moment expansion ( CMX) technique is used to calculate the zero-point energy of an arbitrary system of coupled anharmonic oscillators. When the anharmonic term has the form of a polynomial with respect to the normal coordinates, it is possible to calculate the zero-point energy in a co
We apply renormalized perturbation theory by the moment method to an anharmonic oscillator in two dimensions with a perturbation that couples unperturbed degenerate states. The method leads to simple recurrence relations for the perturbation corrections to the energy and moments of the eigenfunction
