Critical quasiparticle theory: Scaling, thermodynamic and transport properties

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 YbRh$_2$Si$_2$ (YRS), for which we also derive the critical behavior of the specific heat, resistivity, Gr{\" u}neisen coefficient, and the thermopower. The theory accounts very well for the experimental results
