Extremely cold atoms defy entropy and refuse to heat up
Adding energy to a group of ultracold atoms should make them fly away from each other with many different energies, but quantum effects can counteract this

These two panels from The Flash #800 are amazing! Wally West encounters an atomic mirror — so many concepts from quantum physics and optics included here #quantumoptics #coldatoms #quantumphysics
We see Wally West stopped in front of a mysterious white rectangle, his suit ripped and burning after the impact. He thinks “oh the Fresnel diffraction… if it were possible to scale up… to use me as a proxy for an energized particle… then… the waveform scatters. This is what you’d get from a collision with… damn” In the left panel, The Flash head on, posed like a sprinter in the blocks at the start of a 100m race. In the right he races towards the atomic mirror, hoping to break through. His thoughts continue: “A quantum barrier, an interference field to splinter vibrations from their source. Unstitching the speed source from my matter. Mirrors huh? Sure brings to mind a suspect and a solution. See, an atomic mirror’s only efficient at an oblique angle— grazing incidence it’s called — but head on?”
