🧲 Magneto-Optical Trap: Laser Cooling & Atom Trapping Simulator

Simulate a magneto-optical trap: tune laser detuning, magnetic field gradient and beam intensity to laser-cool a cloud of rubidium atoms, watch the Doppler temperature drop and the cloud collapse into a bright trapped core.

ControlsTrap ON/OFF button toggles the magnetic gradient and light forces to show free ballistic expansion vs. recapture; Detuning slider (δ/Γ, -3 to -0.1) sets how far red of resonance the six laser beams sit; Magnetic gradient slider (0-20 G/cm) sets trap stiffness, with the vertical coil axis getting twice the radial gradient as in a real anti-Helmholtz pair; Saturation slider (s0, 0.1-5) sets beam intensity/scattering rate.
