#### Quasi-particle properties in a quasi-two-dimensional electron liquid

(Indian Academy of Sciences, 2008)

We consider the quasi-particle properties such as the effective mass and spin susceptibility of quasi-two-dimensional electron systems. The finite quantum well width effects are incorporated into the local-field factors ...

#### 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

(2002)

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. ...

#### Effective electron-electron interactions and magnetic phase transition in a two-dimensional electron liquid

(Elsevier B.V., 2007)

We investigate the spin-dependent effective electron-electron interactions in a uniform system of two-dimensional electrons to understand the spontaneous magnetization expected to occur at very low density. For this purpose, ...

#### Spin correlations in a quasi-one-dimensional electron gas

(Elsevier BV, 1996)

We study the spin correlations in a quasi-one-dimensional electron gas within the self-consistent-field approximation (SCFA). Electrons confined in a parabolic potential restricted to have free motion in one space dimension, ...

#### 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 ...

#### Simplified calculations of band-gap renormalization in quantum-wells

(Academic Press, 1996)

Non-linear optical properties of photoexcited semiconductor quantum-wells are of interest because of their opto-electronic device application possibilities. Many-body interactions of the optically created electrons and ...

#### 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 ...

#### 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. ...
