From the point of view of its electronic properties, graphene is a zero-gap semiconductor, in which low-E quasiparticles within each valley can formally be described by the Dirac-like hamiltonian At ...

The authors report a strategy to break inversion symmetry in infinite-layer nickelate superconductors through artificial superlattice design. Asymmetric residual oxygen at the interfaces induces ...

A new study has found that metformin, a widely prescribed diabetes drug, may mimic one of exercise's core biological effects in men with prostate cancer, raising levels of a molecule tied to energy ...
