Green's function physics
WebFeb 5, 2024 · Then I calculate the interacting Greens function with an initial guess for its corresponding self energy. G ( E, k) = [ E I − H 0 − Σ I ( k)] − 1. Σ I is a Fock like term and its only a function of momentum (k). The new Greens function is (Dyson equation): G n e w = G 0 + G 0 ∗ Σ I ∗ G. Now my question is how to update the Σ I ( k) WebSchrödinger equation is a linear partial differential equation, so sure, you can use the usual formalism of Green's functions to solve it. First let's recall how the stuff works. Suppose …

It … Web1) where δ is the Dirac delta function . This property of a Green's function can be exploited to solve differential equations of the form L u (x) = f (x) . {\displaystyle \operatorname {L} \,u(x)=f(x)~.} (2) If the kernel of L is non-trivial, then the Green's function is not unique. However, in practice, some combination of symmetry , boundary …
