First Order Perturbation Theory Last update 30/1/10 1. Time Independent Perturbation Theory The purpose of time independent perturbation theory is to estimate the energy levels and wavefunctions for a system which is perturbed from an initial Hamiltonian system with known energy levels and energy ...
The second, based on complex function theory and on eigenprojectors, as is standard in analytic perturbation theory, is a simplified version of well-known results in the literature. The second derivation uses a convenient normalization of the right and left eigenvectors defined in terms of the ...

In terms of the Legendre effective action, we establish the continuum limit to first order, characterising the most general form of such coefficient functions so as to verify universality.doi:10.1007/JHEP06(2020)138Alex MitchellTim R. MorrisJournal of High Energy Physics...
A method for the determination of the symmetry of first-order vectors in Hartree–Fock perturbation theory is developed. This leads to the definition of symmetry-adapted basis vectors to be employed at first order in the perturbation. It is shown that computer time can be saved, to some ...

A code for calculating the depletion sensitivity coefficient of atomic densities is developed on the basis of a first-order generalized perturbation theory. The sensitivity coefficient of atomic density of 244 Cm at 50GWd/T due to the change of cross section is analyzed, and the results show tha...
