摘要

We use the recently developed critical quasipartide theory to derive the scaling behavior associated with a quantum critical point in a correlated metal. This is applied to the magnetic-field induced quantum critical point observed in YbRh_2Si_2, for which we also derive the critical behavior of the specific heat, resistivity, thermo-power, magnetization and susceptibility, the Griineisen coefficient, and the thermal expansion coefficient. The theory accounts very well for the available experimental results.
