Unified formalism for calculating polarization, magnetization, and more in a periodic insulator
In this paper, we propose a unified formalism, using Green's functions, to integrate out the electrons in an insulator under uniform electromagnetic fields. We derive a perturbative formula for the Green's function in the presence of uniform magnetic or electric fields. By applying the for...
