Observation of quantum spin liquids

This post is dedicated to one fascinating topic: quantum spin liquids. In recent decades science has shown us that there are more than the three states of matters we all know: liquid, solid and gas.
In the microscopic world, so tiny that we can see the different particles inside matter, the electrons, neutrons and protons behave like particles and waves at the same time.
At this level, an intrinsic property of matter, the spin, becomes very important and it is key to study quantum magnetism. 
When the spins (small magnetic dipoles) align in one specific direction, the system is ordered as a ferromagnetic spin state. On the contrary, if the spins are disordered, then it is called a quantum spin liquid, and as this state is preserved at very low temperatures, fascinating physics appears.
For a very well structure summary about quantum spin liquids please go HERE, and if you want to get the insight on the topic you can read more HERE.

For the first time a quantum spin liquid has been empirically demonstrated in a mono-crystal of the compound calcium-chromium oxide, by a team at the Helmholty-Zentrum Berlin (for more information please click on the image below).
