Fermi's golden ruleprinciple

A quantum particle like an electron cannot just 'slightly' jump to another level — the transition either happened or it didn't. Fermi's golden rule gives the probability of such an event per second. It's like predicting how often a ball exits a maze through many exits if it is constantly nudged by weak pushes.

How it works

The rule is used to calculate the probability of particle decay, photon emission, nuclear reaction cross sections, and transistor operation. It predicts the rate at which an excited atom emits light and why some transitions are forbidden while others are allowed.

💡 Thanks to this rule, we know why LEDs glow a specific color: electrons and holes meet at a pre-calculated rate.
\Gamma_{i\rightarrow f} = \frac{2\pi}{\hbar} |\langle f|H'|i\rangle|^2 \rho(E_f)
Γ_{i→f} — transition probability per unit time (transition rate), ħ — reduced Planck constant (ħ ≈ 1.0546×10⁻³⁴ J·s), ⟨f|H'|i⟩ — matrix element of the perturbation operator H' between initial |i⟩ and final |f⟩ states, ρ(E_f) — density of final states at energy E_f (number of states per unit energy interval).
