Most materials go from being solids to liquids when
they are heated. One rare counter-example is helium-3, which can
solidify upon heating. This counterintuitive and exotic effect,
known as the Pomeranchuk effect, may now have found its electronic
analog in a material known as magic-angle graphene, says a team of
researchers from the Weizmann Institute of Science led by Prof.
Shahal Ilani, in collaboration with Prof. Pablo Jarillo-Herrero’s
group at the Massachusetts Institute of Technology
(MIT).
