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 ...
Energy-transfer rate in a double-quantum-well system due to Coulomb coupling
We study the energy-transfer rate for electrons in a double-quantum-well structure, where the layers are coupled through screened Coulomb interactions. The energy-transfer rate between the layers (similar to the Coulomb ...
Effective mass enhancement in two-dimensional electron systems: The role of interaction and disorder effects
Recent experiments on two-dimensional (2D) electron systems have found a sharp increase in the effective mass of electrons with decreasing electron density. In an effort to understand this behavior we employ the many-body ...
Plasmon dispersion and damping in double-layer electron systems
(Elsevier Science Ltd, Exeter, United Kingdom, 2000)
We use dynamical local-field corrections to study the plasmon dispersion and damping in double-layer electron systems. The wave vector and frequency-dependent local-fields describing the exchange-correlation effects are ...
