Probably a stupid question, but will we ever have something like a microwave to make things cold? Is there a reason this can't exist?

Laser cooling exists, but I don't suppose you can afford one or want your beer on 2ยฐK
it also helps to be cooling a single atom at a time
My god where does it end with you beer snobs??
A lot of laser coolers were built exactly for cooling single atoms (to do scientific research)
