Hidden order phenomena in uranium compounds, notably exemplified by the heavy-fermion material URu₂Si₂, have long intrigued the condensed matter community. The term “hidden order” describes a phase ...
In matter, any spontaneous symmetry breaking induces a phase transition characterized by an order parameter, such as the magnetization vector in ferromagnets, or a macroscopic many-electron wave ...
