Solving the Schrödinger Equation with Power Anharmonicity
Abstract
We present an application of a nonstandard approximate method---the finite-rank approximation---to solving the time-independent Schrödinger equation for a bound-state problem. The method is illustrated on the example of a three-dimensional isotropic quantum anharmonic oscillator with additive cubic or quartic anharmonicity. Approximate energy eigenvalues are obtained and convergence of the method is discussed.
