Superconductors (materials that conduct electricity without resistance) have fascinated physicists for more than a century. While conventional superconductors are well understood, a new class of ...

To study the interactions between electrons in a material, physicists have come up with a number of tricks over the years. These interactions are interesting, amongst other things, because they lead ...

Mid- and far-infrared birefringent crystals are key functional materials for polarization control, laser technologies, and ...

Researchers have made germanium superconducting for the first time, a feat that could transform computing and quantum technologies. Using molecular beam epitaxy to embed gallium atoms precisely, the ...

Atomic orbitals (red & blue), which determine how far electrons can move around their originating atom in a material, can trap those electrons in place—a new source of frustration that researchers can ...
