Query: Irreversible dynamics of the phase boundary in U(Ru0.9)Rh0.04)2Si2 and
  implications for ordering   We report measurements and analysis of the specific heat and magnetocaloric
effect at the phase boundary into the single magnetic field-induced phase
(phase II) of U(Ru{0.96}Rh{0.04})2Si2, which yield striking similarities to the
valence transition of Yb{1-x}YxInCu4. To explain these similarities, we propose
a bootstrap mechanism by which a structural distortion causes an electric
quadrupolar order parameter within phase II to become coupled to the
5f-electron hybridization, giving rise to a valence change at the transition.
