Exact ground-state properties of one-dimensional electron gas at high density
Vinod Ashokan, Renu Bala, Klaus Morawetz +1
The dynamical response theory is used to obtain an analytical expression for the exchange energy of a quantum wire for arbitrary polarization and width. It reproduces the known for…

Conditions where RPA becomes exact in the high-density limit
Klaus Morawetz, Vinod Ashokan, Renu Bala +1
It is shown that in -dimensional systems, the vertex corrections beyond the random phase approximation (RPA) or GW approximation scales with the power of the Fermi momen…
