Description:
Author(s): Guobao Zhu, Shengyuan A. Yang, Cheng Fang, W. M. Liu, and Yugui Yao We present a general formula of the orbital magnetization of disordered systems based on the Keldysh Green's function theory in the gauge-covariant Wigner space. In our approach, the gauge invariance of physical quantities is ensured from the very beginning, and the vertex corrections are easily inc... [Phys. Rev. B 86, 214415] Published Mon Dec 17, 2012
