(Phys.org) -- Researchers at Stanford have been investigating the special properties of a Josephson junction when constructed as hybrid superconducting-topological insulator devices and have found what appears to be some ...
We study the movement of incredibly small things. How small is small? Think smaller than "nano." Think smaller than atoms themselves. We measure the infinitesimally small shifts in the positions of atoms to electrical forces. ...
