## Abstract Landau quasiparticle (qp) theory may be extended into the nonβFermi liquid regime of metallic compounds near a quantum critical point (QCP), provided the width of the quasiparticle states is less than their energy. Sufficiently far from the QCP, when the critical fluctuations are nonβin
Quantum oscillations of the transverse magnetoresistance have been observed in the heavy fermion metal UPt, in fields up to 24.5 T applied in the basal plane, providing the first observation of the quasiparticle Fermi surface above the metamagnetic transition. The observed quasiparticle masses remai
