How does order emerge?

12 marzo 2015

Scientists have analyzed how fast order can appear in a quantum-mechanical system. During the freezing of water, the initially unordered molecules start to form an ordered crystal, namely ice. During this phase transition, they rearrange from an unordered into a more ordered state. This setting naturally poses one important question: How long does this phase transition take, i.e. how long does it take for each molecule to find its place in the crystal?
