Perspective on "Inhomogeneous electron gas"

Theoretical Chemistry Accounts: Theory, Computation, and Modeling (Theoretica Chimica Acta), 2000
The Hohenberg—Kohn theorems in “Inhomogeneous electron gas” established a whole new perspective for the study of electronic structure theory and marked the birth of modern density functional theory (DFT). In our view, DFT and wavefunction theories complement each other. Starting with the invention of the Kohn—Sham method a fruitful synthesis of DFT and

NOVEL ELECTRON GAS SYSTEMS

International Journal of Modern Physics B, 1999
We review recent progress on the physics of electrons in the bilayered electron gas, relevant to coupled quantum wells in GaAs/AlGaAs heterostructures. First, we focus on the phase diagram of a symmetric bilayer at T=B=0, obtained by diffusion Monte Carlo simulations.

The Electron Gas

2004
Abstract The study of the interacting electron gas moving in a charge-compensating background of positively charged ions is central in this book. Not only is this system a model of the solids that surround us, such as metals, semiconductors, and insulators, but historically this system played a major role as testing ground for the ...

Superconductivity in the dilute electron gas

Physical Review B, 1988
We determine the effective interaction of quasiparticles on the Fermi surface for the electron gas in a rigid positive background. The quasiparticle scattering amplitude is calculated from the two coupled Bethe-Salpeter equations for the two-particle vertex functions in the particle-hole (p-h) channels for densities from r/sub s/ = 1 to r/sub s/ = 37 ...

Tetragonal symmetry in the electron gas

Physical Review B, 1992
Two transitions to localized charge density at intermediate and low densities are obtained for the three-dimensional (3D) electron gas in the deformable jellium. At very low densities, where the second transition occurs, the tetragonal structure is obtained. A discontinuity in the coupling parameter \ensuremath{\Gamma} appears at both transition points.

Electron gas in magnetic fields

2000
When a magnetic field is applied to an otherwise freely moving electron, the classical cyclotron motion perpendicular to the field is quantized into discrete Landau levels. Magnetic fields strongly influence the magnetic susceptibility and transport properties of ordinary (i.e.

The Electron Gas

2016
In this chapter we consider the electron gas, assumed to behave as a perfect gas. We discuss the equation of state in the simple case of a perfect gas, the gas pressure, and mean molecular weight, and the chapter concludes with a discussion of the phenomenon of degeneracy.

Electron-electron momentum relaxation in a two-dimensional electron gas

Physical Review B, 1995
Evolution of sharp angular distributions in the degenerate two-dimensional gas of colliding electrons has been shown to occur essentially otherwise than in the three-dimensional gas. As early as after a few collisions the electron distribution function becomes antisymmetric in momentum, conserving, practically, its sharpness.

Electron-electron interactions in the two-dimensional electron gas in silicon

Physical Review B, 1993
We have measured the magnetocapacitance of silicon metal-oxide-semiconductor field-effect transistors in the high-field extreme quantum limit, where only the lowest Landau level is partially occupied and the thermodynamic density of states of two-dimensional electrons is negative.
