A simulation study of a model that mimics certain colloidal particles reveals a surprising low-temperature triumph of entropy, whereby the liquid state persists down to zero temperature.
In classical physics there is no such thing as a thermodynamically stable liquid phase at 0 K, as any liquid will freeze into a crystalline solid at sufficiently low temperatures1,2,3,4. In the real world the only exception to this is helium, for which quantum fluctuations stabilize the liquid state down to absolute zero. Liquids freeze upon cooling because energy eventually dominates over entropy, so at adequately low temperatures the crystalline state — which minimizes its energy by carefully packing the molecules — has a lower free energy than the liquid state.
