One-component order parameter in URu(2)Si(2) uncovered by resonant ultrasound spectroscopy and machine learning

The unusual correlated state that emerges in URu(2)Si(2) below T(HO) = 17.5 K is known as “hidden order” because even basic characteristics of the order parameter, such as its dimensionality (whether it has one component or two), are “hidden.” We use resonant ultrasound spectroscopy to measure the s...
