PDF-Introduction to perturbation methods

1 What are perturbation methods Perturbation methods are methods which rely on there being a dimensionless parameter in the problem that is relatively small 1 The most common example you may have seen before is that of highReynolds number 57357uid m.

Perturbation Theory is an important and powerful method in physics. It enables us to make progress when a physical system is too complicated to be analyzed exactly. The essential idea is to solve the behavior in steps. First we approximate the system by some simple Hamiltonian whose Schrödinger equation we know how to solve. Then we add the bit missed out, and use perturbation theory to calculate how our previous results (energy . Hayato. . Motohashi. & . Teruaki. . Suyama. . (.
