Approximation Method

  • 8 min read

Perturbation theory is a powerful tool in quantum mechanics used to study systems where the Hamiltonian can be separated into a known part \(H_0\) and a small perturbation \(H'\). The goal is to find approximate solutions to the Schrödinger equation for the full Hamiltonian \(H = H_0 + H'\) by treating the perturbation as a small correction to the known system.

Want to add diagrams, charts and visualizations in your post?
It is possible and guess what? It’s not that difficult thanks to Mermaid.
All you need to keep in mind is you’ll have to wrap your Mermaid markup in a div with class mermaid.
Here is a simple example of a basic flowchart,
