method of approximation
111Discrete delta-potential method — The discrete delta potential method is a combination of both numerical and analytic method used to solve the Schrödinger equation the main feature of this method is to obtain first a discrete approximation of the potential in the form: V(r) = ∑… …
112Random phase approximation — (RPA) is one of the most often used methods for describing the dynamic electronic response of systems. In RPA, electrons are assumed to respond only to the total electric potential V (r) which is the sum of the external perturbing potential V… …

114Background field method — In theoretical physics, background field method is a useful procedure to calculate the effective action of a quantum field theory by expanding a quantum field around a classical background value B :: phi(x) = B(x) + eta (x).After this is done,… …
115temporal method — A method of converting a foreign currency involved in a transaction in which the local currency is translated at the exchange rate in operation on the date on which the transaction occurred. If rates do not fluctuate significantly, an average for …
