Study of numerical accuracy of quadratic penalty method in covariant density functional theory

Abstract EN

The solution of a system of coupled partial differential equations in density functional theory will always provide a solution that corresponds to a minimum.

Quadratic penalty method is applied to obtain the solution (excited solution) at any desired point in deformation space.

The accuracy of this method will be investigated and its dependence on the number of oscillator shells and number of Gauss-Hermit integration points.
