重电子材料中的普适行为

Universal Behavior in Heavy Electron Materials

Yi-feng Yang, David Pines

摘要:

我们发现,一个特别简单的标度表达式描述了一种新的量子物质态,近藤费米液体(KL)在重电子材料的形成。出现在$T^*$作为本地化f电子和传导电子的集体相干杂交的结果,KL具有非朗道态密度变化为$(1-T/T^*)^{3/2}[1+\ln(T^*/T)]$。我们发现,四个独立的实验探针验证了这种标度行为,并为CeIrIn $_5$的KL态密度是在极好的协议与最近的微观计算杂交在这种材料中的Shim,Haule和Kotliar。

英文摘要:

We present our finding that an especially simple scaling expression describes the formation of a new state of quantum matter, the Kondo Fermi liquid (KL) in heavy electron materials. Emerging at $T^*$ as a result of the collective coherent hybridization of localized f electrons and conduction electrons, the KL possesses a non-Landau density of states varying as $(1-T/T^*)^{3/2}[1+\ln(T^*/T)]$. We show that four independent experimental probes verify this scaling behavior and that for CeIrIn$_5$ the KL state density is in excellent agreement with the recent microscopic calculations of hybridization in this material by Shim, Haule, and Kotliar.
