PhysicsOdd quantum property may let us chill things closer to absolute zero We can already cool objects with fridges and with lasers. Now there is a third cooling technique involving special quantum states – and it could, in theory, allow us to reach the lowest temperatures yet 51¶¯Âþ
PhysicsRecord broken for the coldest temperature reached by large molecules Four-atom molecules glued together by microwaves have broken the record for being the most complicated molecule to reach temperatures just billionths of a degree away from absolute zero 51¶¯Âþ
