A deviation from the second law of thermodynamics has been demonstrated experimentally for the first time. Denis Evans of the Australian National University and colleagues have shown that entropy can be consumed - rather than generated - in small systems over short periods of time. The achievement fulfils a prediction made by Evans and colleagues ten years ago (G Wang et al 2002 Phys. Rev. Lett. 89 050601). |
