The quantum double well anharmonic oscillator in an external field
The aim of this paper is twofold. First of all, we study the behaviour of the lowest eigenvalues of the quantum anharmonic oscillator under influence of an external field. We try to understand this behaviour using perturbation theory and compare the results with numerical calculations. This brings us to the second aim of improving the method used to carry out the numerical calculations.
متن کاملZeros of eigenfunctions of some anharmonic oscillators
where P is a real even polynomial with positive leading coefficient, which is called a potential. The boundary condition is equivalent to y ∈ L(R) in this case. It is well-known that the spectrum is discrete, and all eigenvalues λ are real and simple, see, for example [3, 14]. The spectrum can be arranged in an increasing sequence λ0 < λ1 < . . .. Eigenfunctions y are real entire functions of o...
متن کاملNumerical Analysis of Spectral Properties of Coupled Oscillator Schrodinger Operators I. Single and Double Well Anharmonic Oscillators
We describe several methods for computing many eigenvalues and eigenfunctions of a single anharmonic oscillator Schrodinger operator whose potential may have one or two minima. One of the methods requires the solution of an ill-conditioned generalized eigenvalue problem. This method has the virtue of using a bounded amount of work to achieve a given accuracy in both the single and double well r...
متن کاملQuantum anharmonic oscillator and its statistical properties
The simple quantum harmonic oscillator is an excellent model of many physical systems, e.g. electromagnetic field. The excitation particles or quanta of the electromagnetic field are called photons [1, 2] Moreover it applies for systems of atoms (ions, nuclei) in ideal crystals interacting via harmonic attractive force, etc. In the latter case the elementary excitation particles of vibrations o...
متن کاملDispersive hyperasymptotics and the anharmonic oscillator
Hyperasymptotic summation of steepest-descent asymptotic expansions of integrals is extended to functions that satisfy a dispersion relation. We apply the method to energy eigenvalues of the anharmonic oscillator, for which there is no known integral representation, but for which there is a dispersion relation. Hyperasymptotic summation exploits the rich analytic structure underlying the asympt...
