In physics, things exist in phases, such as solid, liquid and gas states. When something crosses from one phase to another, we talk about a phase transition—like water boiling into steam, turning from liquid to gas.

URu2Si2 is a metal that belongs to the family of heavy-fermion compounds in which several quantum phases (e.g., magnetism and superconductivity) can compete or coexist. These metals exhibit small energy scales that are easy ...
Physicists at the U.S. Department of Energy's Ames Laboratory have successfully performed measurements of an iron-based superconductor in an important but difficult-to-reach regime where critical quantum fluctuations dominate ...
