Quantum & Atomic Physics

Lamb Shift

A small energy difference between the 2s1/2 and 2p1/2 states of hydrogen caused by quantum vacuum fluctuations.

ΔE_Lamb ≈ 1057 MHz (for Hydrogen 2s1/2 and 2p1/2) MHz or eV
Quantum & Atomic Physics

Laser Cooling

A technique using photon momentum from red-detuned laser beams to slow down moving gas atoms, cooling them to microkelvin temperatures.

F_force = ℏ k γ (I / I_sat) / (1 + 4 (Δ ± k v)² / γ²) μK or nK (Temperature)

Lyman Series

The hydrogen spectral series resulting from electron transitions dropping from higher excited states down to the ground state (n=1).

1 / λ = R_H (1 / 1² - 1 / n_i²), n_i = 2, 3, 4... Ultraviolet Wavelengths (nm)
