Critical quasiparticle theory: Scaling, thermodynamic and transport properties
Abstract
We use the recently developed critical quasiparticle theory to derive the scaling behavior associated with a quantum critical point (QCP) in a correlated metal. This is applied to the magnetic-field induced QCP observed in YbRh2Si2 (YRS), for which we also derive the critical behavior of the specific heat, resistivity, Gr\" uneisen coefficient, and the thermopower. The theory accounts very well for the experimental results
