临界准粒子理论:标度、热力学和输运性质

Critical quasiparticle theory: Scaling, thermodynamic and transport properties

Elihu Abrahams, Peter Woelfle

摘要:

我们利用最近发展起来的临界准粒子理论推导了关联金属中与量子临界点(QCP)相关的标度行为。将其应用于在YbRh $_2$ Si $_2$(YRS)中观察到的磁场感生QCP,导出了比热、电阻率、Gr{\”u}neisen系数和热电势的临界行为。这个理论很好地解释了实验结果

英文摘要:

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
