Role of commensurate and incommensurate low-energy excitations in the paramagnetic to hidden-order transition of URu${}_2$Si${}_2$

We report low-energy inelastic neutron scattering data of the paramagnetic (PM) to hidden-order (HO) phase transition at $T_0=17.5\mathrm{K}$ in URu${}_2$Si${}_2$. While confirming prev…
