Second-order nonlocal shifts of scattered wave-packets: What can be measured by Goos-Hänchen and Imbert-Fedorov effects ?
K. Morawetz
The scattering of wavepackets with arbitrary energy dispersion on surfaces has been analyzed. Expanding up to second order in scattering shifts, it is found that besides the known…
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…
Extended quasiparticle Padé approximation for non-Fermi liquids
K. Morawetz
The extended quasiparticle picture is adapted to non-Fermi systems by suggesting a Padé approximation which interpolates between the known small scattering-rate expansion and the d…
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…
Interplay of viscosity and surface tension for ripple formation by laser melting
K. Morawetz, S. Trinschek, E. L. Gurevich
A model for ripple formation on liquid surfaces exposed to an external laser or particle beam and a variable ground is developed. The external incident beam is hereby mechanically…
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…
