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
PhysicsHeating and cooling seem to be fundamentally different, not opposites Conventional thermodynamics says that heating and cooling are essentially mirror images of each other, but an experiment with a tiny silica sphere suggests otherwise 51¶¯Âþ
