Ground-state properties of electron-electron biwire systems
Rajesh O. Sharma, N. D. Drummond, Vinod Ashokan +2
The correlation between electrons in different quantum wires is expected to affect the electronic properties of quantum electron-electron biwire systems. Here, we use the variation…
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…
One-dimensional electron fluid at high density
Vinod Ashokan, N. D. Drummond, K. N. Pathak
We calculate the ground-state energy, pair correlation function, static structure factor, and momentum density of the one-dimensional electron fluid at high density using variation…
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…
