minus-square@[email protected]linkfedilink0•1 year agoCan I get an ELI5 of this principle? I read the Doppler cooling part but I can’t connect the dots.
minus-square@[email protected]linkfedilink3•1 year agoHeat energy is the amount of particle wiggling. With precisely tuned and oriented lasers you can clamp a particle in space, thus prevent it from wiggling. No wiggling -> very cold.
