URu2Si2中的隐序跃迁和相干Kondo晶格的出现

Hidden Order Transition in URu2Si2 and the Emergence of a Coherent Kondo Lattice

Ting Yuan, Jeremy Figgins, Dirk K. Morr

摘要:

使用大N方法,我们证明了在最近的扫描隧道光谱实验中测量的微分电导和准粒子干涉图案(A.R. Schmidt等人,Nature 465,570(2010); P. Aynajian等人,PNAS 107,10383(2010))与在其隐藏的有序跃迁(HOT)之下出现的相干近藤晶格一致。它的形成是由一个显着增加的准粒子寿命,这可能会出现一个未知的序参量在HOT。

英文摘要:

Using a large-N approach, we demonstrate that the differential conductance and quasi-particle interference pattern measured in recent scanning tunneling spectroscopy experiments (A.R. Schmidt et al. Nature 465, 570 (2010); P. Aynajian et al., PNAS 107, 10383 (2010)) in URu2Si2 are consistent with the emergence of a coherent Kondo lattice below its hidden order transition (HOT). Its formation is driven by a significant increase in the quasi-particle lifetime, which could arise from the emergence of a yet unknown order parameter at the HOT.
