Wire width and density dependence of the crossover in the peak of the static structure factor from $2 k_{F}$ $\to$ $4 k_{F}$ in one-dimensional paramagnetic electron gases

Ankush Girdhar, Vinod Ashokan, Rajesh O. Sharma +2

We use the variational quantum Monte Carlo (VMC) method to study the wire width ( $b$ ) and electron density ( $r_{s}$ ) dependences of the ground-state properties of quasi-one-di…

Electron correlation and confinement effects in quasi-one-dimensional quantum wires at high density

Ankush Girdhar, Vinod Ashokan, N. D. Drummond +2

We study the ground-state properties of ferromagnetic quasi-one-dimensional quantum wires using the quantum Monte Carlo (QMC) method for various wire widths $b$ and density paramet…

Conditions where RPA becomes exact in the high-density limit

Klaus Morawetz, Vinod Ashokan, Renu Bala +1

It is shown that in $d$ -dimensional systems, the vertex corrections beyond the random phase approximation (RPA) or GW approximation scales with the power $d - β - α$ of the Fermi momen…
