WebWe employ Green’s function method for describing multiband models with magnetic impurities and apply the formalism to the problem of chromium impurities adsorbed onto a carbon nanotube. Density functional theory is used to determine the bandstructure, which is then fit to a tight-binding model to allow for the subsequent Green’s function description.

WebMar 24, 2024 · Generally speaking, a Green's function is an integral kernel that can be used to solve differential equations from a large number of families including simpler examples such as ordinary differential … WebApr 12, 2024 · The Green's function corresponding to Eq. (2) is a function G ( x, x0) satisfying the differential equation. (3) L [ x, D] G ( x, x 0) = δ ( x − x 0), x ∈ Ω ⊂ R, where x0 is a fixed point from Ω. The function in the right-hand side the Dirac delta function. This means that away from the point x0. The primary use of Green's functions in mathematics is to solve non-homogeneous boundary value problems. In modern theoretical physics, Green's functions are also usually used as propagators in Feynman diagrams; the term Green's function is often further used for any correlation function.
