Physicists have developed a new way to control the transport of electrical currents through high-temperature superconductors — materials discovered nearly 30 years ago that lose all resistance to electricity at commercially attainable low temperatures.

Researchers have announced the observation of a dynamic Mott transition in a superconductor. The discovery experimentally connects the worlds of classical and quantum mechanics and illuminates the mysterious nature of the Mott transition. It also could shed light on non-equilibrium physics, which is poorly understood but governs most of what occurs in our world. Th
