Phonon confinement and screening effects on the polaron energy in quantum wires
(Institute of Physics Publishing Ltd., 1995)
We study the contribution of confined phonons to the polaron energy in quantum-well wires. We use a dispersionless, macroscopic continuum model to describe the phonon confinement in quantum wires of square cross section. ...
Collective modes in a quasi-one-dimensional, two-component electron liquid
(Pergamon Press, 1994)
Under favorable conditions, a new collective mode besides the usual plasmons may exist in degenerate electron-hole liquids. We calculate the dispersion and damping of this new mode (called the acoustic plasmon mode) in a ...
Many-body effects in the Coulomb drag between low density electron layers
(Elsevier Science, 2003)
Recent Coulomb drag experiments in low-density double-layer electron systems have the power of distinguishing various many-body formulations of the effective interactions. In this work we theoretically study the correlation ...
Many-body properties of a disordered charged Bose gas superlattice
(Academic Press, 2000)
We study some many-body properties of a disordered charged Bose gas (CBG) superlattice-an infinite array of CBG layers each of which containing disorder. The latter is assumed to cause collisions with the charged bosons, ...
Short-range correlations in coupled quantum-wire systems
We study the contact values of the inter-wire pair-correlation function in electron-electron and electron-hole double-wire systems. For this purpose the ladder approximation as generalized to multicomponent systems is used. ...
