Spin-Chain Incipient Magnetocaloric Effect and Rare-Earth Controlled Switching in the Haldane-Chain System, R2BaNiO5
Mohit Kumar, Gourab Roy, Sayan Ghosh +3
We have experimentally investigated the magnetocaloric effect (MCE) of a prototype spin-frustrated one-dimensional spin-chain system, the famous Haldane-chain system, R2BaNiO5 (R =…
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…
Wire width and density dependence of the crossover in the peak of the static structure factor from 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 () and electron density () 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 and density paramet…
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…
