The exact universal exchange-only local field factor of the uniform electron gas and its near-cancellation by parallel-spin correlation near 2kF

Carl A. Kukkonen

The exchange-only local field factor Gx(q,omega) of the uniform electron gas is exact and universal, a single curve at every density when q is measured in units of kF and omega in…

Charge density waves and enhanced superconductivity in the electron-hole gas: a plausible, simple, physically intuitive model

Carl A Kukkonen

A neutral degenerate plasma of equal numbers of electrons and positively charged fermions (holes) -- the electron-hole gas -- is studied using a simple, physically motivated two-pa…

Charge density waves and superconductivity in the electron-positive fermion gas using a simple intuitive model. Part I: The model, instabilities, and phase diagram

Carl A. Kukkonen

The electron-positive fermion gas in three dimensions and is modeled as two independent fermion gases interacting via the coulomb interaction. The main advantage of the simpl…
