Entropy measurements reveal exotic effect in ‘magic-angle’ graphene

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 analogue in a material known as magic-angle graphene, say researchers.
