The one clue that theorists have is that the strange metal phase is associated with a low-temperature transport behavior called Planckian dissipation [ 2, 3 ]. The same association is found by Jarillo-Herrero and colleagues in magic-angle graphene, providing further evidence that strange metals are united by a fundamentally new form of transport that theorists are busy trying to characterize.

Feb 20, 2020 · Experiments on magic-angle graphene reveal a “strange metal” phase and transport behavior consistent with so-called Planckian dissipation. February 20, 2020. Magic-angle graphene captured the attention of condensed-matter physicists in 2018 when it was discovered that this material—made of two sheets of graphene with slightly misaligned lattice orientations—is a superconductor. The mechanical exfoliation of graphite to form graphene ([ 1 ][1]) opened the door for isolating and stacking other two-dimensional (2D) materials to build devices with specific functionality. In 2010, it was discovered that introducing a twist between the crystal orientations of two stacked graphene layers can drastically change the electronic properties of the material ([ 2 ][2]), and ...
