Scientists document the presence of quantum spin liquids, a never before seen state of matter12/9/2021 Repost by PHYS ORG.

Instead it has all to do with electrons and magnetism. In a regular magnet, all electrons spin in the same or alternate directions: they are in an ordered state; which creates magnetism. In a quantum spin liquid, they are constantly moving around. Theorized in 1973, it has only now been achieved in reality by Havard scientists in collaboration with scientists from University of Innsbruck and QuEra computing in Boston. This state of matter could possibly be used to form topological qubits which can lead to the future of quantum computers. Repost by PHYS ORG. Original article by Nagoya University.

Using these effects, thermoelectric materials are used in cooling devices and obviously to generate current. Peltier conductivity(P) relates the temperature difference to the thermoelectric current and scientists don’t know how large it can get. Researchers from Nagoya university recently found a material in which the P value was 100x the value found in other thermoelectric materials. This opens avenues for low cost machines such as a low cost MRI machine due to the fact that a large current can be produced with just a small temperature difference. Credit: Akitoshi Nakano
