Journal Article

We report thermodynamic measurements in a magnetic-field-driven quantum critical point of a heavy fermion metal, YbRh₂Si₂. The data provide evidence for an energy scale in the equilibrium excitation spectrum that is in addition to the one expected from the slow fluctuations of the order parameter. Both energy scales approach zero as the quantum critical point is reached, thereby providing evidence for a new class of quantum criticality.
