Numerical Methods Project: Feynman path integrals in quantum
... endpoints become unimportant. Also the analytical solution for this problem is well known, which means that error estimating will be straight forward. The main characteristic is the energilevels, which are given by En = ~ω( 12 + n) these are the main objective to reproduce using the methods describe ...

Superselection Rules - Philsci
... The concept of SSR should be contrasted with that of an ordinary selection rule (SR). The latter refers to a dynamical inhibition of some transition, usually due to the existence of a conserved quantity. Well known SRs in Quantum Mechanics concern radiative transitions of atoms. For example, in case ...
