Title:
Calculation of resonant states using an optimal path of continuous extension of the bound states: The cubic and quartic energy distortion of the harmonic oscillator
Description:
<jats:p>Resonant eigenvectors are calculated within the framework of the complex rotation theory using a continuous deformation and extension of the localized bound states through the potential barrier. The vector is obtained by gradually increasing the basis size and defining for each new basis a lesser perturbation path which best verifies the complex extension of the virial theorem. The modifications resulting from the increase of the basis set N and from the variations of the optimal rotation angle θ(N) are well handled using a Bloch wave operator formulation.</jats:p>
