Numerical Constructions of Perturbation Series in Quantum Mechanics

چکیده
Our several recent improvements of the current textbook (so called Rayleigh-Schrödinger) perturbative representation of bound states are reviewed. They were all inspired by an adaptive re-split H(λ) = H + λH of the Hamiltonian. Their feasibility is facilitated by the use of nonstandard bases and by the flexibility of normalization of the wave functions ψ(λ).

Mo” ller–Plesset convergence issues in computational quantum chemistry
The Hartree–Fock self-consistent-field approximation has provided an invaluable conceptual framework and a standard computational procedure for atomic and molecular quantum theory. Its shortcomings are significant however, and require remediation. Mo”ller–Plesset perturbation theory offers a popular correction strategy: it formally expands eigenfunctions and eigenvalues as power series in a cou...
متن کاملNonlinear transversely vibrating beams by the homotopy perturbation method with an auxiliary term
This paper presents the high order frequency-amplitude relationship for nonlinear transversely vibrating beams with odd and even nonlinearities, using Homotopy Perturbation Method with an auxiliary term (HPMAT). The governing equations of vibrating buckled beam, beam carrying an intermediate lumped mass, and quintic nonlinear beam are investigated to exhibit the reliability and ability of the p...
متن کاملHigh order perturbation study of the frustrated quantum Ising chain
In this paper, using high order perturbative series expansion method, the critical exponents of the order parameter and susceptibility in transition from ferromagnetic to disordered phases for 1D quantum Ising model in transverse field, with ferromagnetic nearest neighbor and anti-ferromagnetic next to nearest neighbor interactions, are calculated. It is found that for small value of the frustr...
متن کاملPull-in behavior analysis of vibrating functionally graded micro-cantilevers under suddenly DC voltage
The present research attempts to explain dynamic pull-in instability of functionally graded micro-cantilevers actuated by step DC voltage while the fringing-field effect is taken into account in the vibrational equation of motion. By employing modern asymptotic approach namely Homotopy Perturbation Method with an auxiliary term, high-order frequency-amplitude relation is obtained, then the infl...
متن کاملScaling, Perturbative Renormalization and Analyticity for the Standard Map and Some Generalizations
We summarize some numerical works on the analyticity properties of the perturbative series (e. g. Lindstedt series) for some simple discrete-time hamiltonian systems like the so-called \standard map" and generalizations. We stress the relevance of our results for the development of a renormalization group picture based on perturbation theory.
