Tests on the Homogeneous Electron Gas

  In an earlier piece of work[3] Louisa Fraser performed a series of QMC calculations on the homogeneous electron gas (HEG). In these calculations she used a simplified version of the new interaction of Eq.().

 

The charge density, , in the HEG is by definition uniform and so the integral in the second term of Eq.() reduces to a constant that is dependent only on the geometry of the Wigner-Seitz cell and the value of . Therefore, the calculations used in Ref.[3] provide a first, simplified test of the full new interaction in Eq.().
