Wilson数值重整化群与AdS_3几何

Wilson's numerical renormalization group and AdS_3 geometry

Kouichi Okunishi

摘要:

本文讨论了在AdS_3时空背景下,近藤杂质问题的Wilson数值重整化群(NRG)与场论之间的关系,其中径向坐标是有效质量尺度的控制参数.我们发现Wilson NRG可以用边界Rindler场来描述,并且Wilson NRG的截止参数λ与AdS半径L的关系为λ= 2kF/ωL,其中kF为有效费米波数。还发现Rindler空间是用a=π/kF的格空间离散的。

英文摘要:

We discuss the relation between the Wilson's numerical renormalization group(NRG) for the Kondo impurity problem and a field theory in the background AdS_3 space time, where the radial coordinate plays a role of the controlling parameter of the effective mass scale. We find that the Wilson NRG can be described by the boundary Rindler field and then the cutoff parameter λof the Wilson NRG is related to the AdS radius L through λ= 2k_F/ωL, where k_F is the effective Fermi wave number. It is also found that the Rindler space is discretized with the lattice space of a=π/k_F.
