Material low-temperature properties can be predicted from its symmetry
A sphere looks the same no matter how it is rotated. Squash it on one side, however, and this symmetry is broken. A similar change from a high-symmetry state to a low-symmetry state defines many phase transitions ...

The changing phase of quantum materials: Theoretical model could aid search for ideal material for quantum computers
Matter is categorized as either conductive, semi-conductive or resistive to the flow of electrons based on its bulk properties. However, physicists have now predicted a new state of matter in which the bulk ...

Even graphene has weak spots: Theorists find junctions in polycrystalline graphene sap its strength
(Phys.org) —Graphene, the single-atom-thick form of carbon, has become famous for its extraordinary strength. But less-than-perfect sheets of the material show unexpected weakness, according to researchers ...
