Rayleigh--Ritz method, secular determinant, and anharmonic oscillators

Journal Article · · Phys. Rev., D, v. 8, no. 10, pp. 3487-3492
The standard Rayleigh-Ritz procedure yielding the successive truncations of the secular determinant is applied to any anharmonic oscillator (x/sup 2m/ and in any finite number of dimensions). In this way one obtains a rigorously convergent as well as numericslly very effective approximation procedure for any eigenvalue and eigenvector of the above mentioned Hamiltonians. (auth)
