Beyond absolute zero

A recent article in Science Magazine has hinted that it is theoretically possible to go beyond absolute zero and have negative Kelvin temperatures. This has some interesting potential implications for the design of devices involving work and heat transfers. This article attempts to explain the science behind the recent research and explores briefly a world of negative absolute temperatures.
