Fig. 2: Diagrammatic representation for the side-jump contribution.
From: Critical enhancement of the spin Hall effect by spin fluctuations
Solid (wavy) lines are the electron Green’s functions (the SF propagators). Squares (circles) are the spin (charge) current vertices, with filled symbols representing the velocity correction with \({{{{\mathcal{F}}}}}_{2}\), i.e., side jump. Filled triangles are the interaction vertices with \({{{{\mathcal{F}}}}}_{0,1}\). Adapted from Okamoto, S., Egami, T. & Nagaosa, N. Phys. Rev. Lett. 123, 196603 (2019).
