Materials that exhibit topological phases can be classified by their dimensionality, symmetries and topological invariants to form conductive-edge states with peculiar transport and spin properties. For example, the quantum ...
Researchers at the University of Antwerp report how higher-order periodic modulations called supermoiré caused by the encapsulation of graphene between hexagonal boron nitride affect the electronic and structural properties ...

New physical behavior, such as Mott insulating behavior, unconventional superconductivity and quantum spin liquid behavior, occurs when electrons inside a material interact with each other. When electrons are confined to ...
Move over Godzilla vs. King Kong—this is the crossover event you've been waiting for. Well, at least if you're a condensed matter physicist. Harvard University researchers have demonstrated the first material that can have ...
