Ray of light could lead to next generation of superconductors

A superconductor, which can move electrical energy with no wasteful resistance, is the holy grail of cost-effective, efficient, and "green" power production. Unlike traditional conductors such as copper or silver, which waste ...

Quantum matter breakthrough: Tuning density waves

Scientists at EPFL have found a new way to create a crystalline structure called a "density wave" in an atomic gas. The findings can help us better understand the behavior of quantum matter, one of the most complex problems ...

Heavy fermions get nuclear boost on way to superconductivity

In a surprising find, physicists from the United States, Germany and China have discovered that nuclear effects help bring about superconductivity in ytterbium dirhodium disilicide (YRS), one of the most-studied materials ...

Understanding room-temperature superconductivity

Room-temperature superconductors could transform everything from electrical grids to particle accelerators to computers, but researchers are still trying to understand how these materials function on the atomic level.

Quantum fractals at the border of magnetism

U.S., German and Austrian physicists studying the perplexing class of materials that includes high-temperature superconductors are reporting this week the unexpected discovery of a simple "scaling" behavior in the electronic ...
