minus-square@Scrappy@feddit.nllinkfedilink3•10 months agoCan I get an ELI5 of this principle? I read the Doppler cooling part but I can’t connect the dots.
minus-square@hstde@feddit.delinkfedilink17•10 months 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.
