When research projects involve super-cooling a substance, after you’ve done as much as you can with convective cooling, researchers will sometimes use lasers to cancel out vibrations within the substance, and cancelling vibrations essentially equals cooling.
What if me make a heat laser? /s
You joke, but actually that is a thing.
