Existe-t-il un autre état?
Ben oui! Extrait de la renversante nouvelle:
Solid, liquid or gas — we encounter these three classic states of matter every day. It is difficult to imagine that substances could simultaneously exhibit properties of two of these states.
Yet, precisely such a phenomenon is possible in the realm of quantum physics, where matter can display behaviors that seem mutually exclusive. Supersolidity is one example of such an exotic state.
In a supersolid, atoms are arranged in a crystalline pattern while at the same time behaving like a superfluid, in which particles move without friction.
Until now, supersolidity was merely a theoretical construct.
But in the Mar. 2 issue of the journal Nature, two teams of researchers report the successful production of a supersolid state.
