Dimensional reduction of the Luttinger-Ward functional for spin-degenerate $D$-dimensional electron gases

D. Miserev, J. Klinovaja, D. Loss

We consider an isotropic spin-degenerate interacting uniform $D$-dimensional electron gas (DDEG) with $D>1$ within the Luttinger-Ward (LW) formalism. We derive the asymptotically…
