Correlation effects in one-dimensional metallic quantum wires under various confinements
Vidit Gangwar, Vinod Ashokan, Ankush Girdhar +3
Dynamical response theory is used to investigate various transverse confinements on electron correlations in the ground state of a ferromagnetic one-dimensional quantum wire for di…
Electronic quantum wires in extended quasiparticle picture
Klaus Morawetz, Vinod Ashokan, Kare Narain Pathak +2
A one-dimensional quantum wire of Fermions is considered and ground state properties are calculated in the high density regime within the extended quasiparticle picture and Born ap…
Off-shell selfenergy for 1-D Fermi liquids
Klaus Morawetz, Vinod Ashokan, Kare Narain Pathak +1
The selfenergy in Born approximation including exchange of interacting one-dimensional systems is expressed in terms of a single integral about the potential which allows a fast an…
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…
Dependence of structure factor and correlation energy on the width of electron wires
Vinod Ashokan, Renu Bala, Klaus Morawetz +1
The structure factor and correlation energy of a quantum wire of thickness are studied in random phase approximation and for the less investigated region . Using…
