Spin correlations in the low-density electron system
(1993-02/15)
The authors have calculated the spin susceptibility x(q,) within a microscopic model over the full range of densities of the electron liquid in the paramagnetic state. Electron-electron interactions are described by static ...
Temperature dependent resistivity in the low-resistance region for diffusive transport in two dimensions
(APS through AIP, 2004-12/15)
The interpretation of the metal-insulator transition phenomena in disordered two-dimensional electron systems in terms of density-dependent scaling variables suggests the existence of a quantum critical point at some ...
Quantum critical behavior in the insulating region of the two-dimensional metal-insulator transition
(American Physical Society by AIP, 2007-11/15)
We show that the quantum critical point associated with the metal-insulator transition phenomenon in two dimensions controls an extended critical region encompassing not only the usual quantum critical sector but also a ...
Two-component scaling near the metal-insulator bifurcation in two dimensions
(APS through AIP, 2003-05/15)
We consider a two-component scaling picture for the resistivity of two-dimensional (2D) weakly disordered interacting electron systems at low temperature with the aim of describing both the vicinity of the bifurcation and ...
Density dependence of critical magnetic fields at the metal-insulator bifurcation in two dimensions
(APS through AIP, 2003-01/15)
The density dependence of the critical in-plane magnetic field Bc at the bifurcation of the resistivity of two-dimensional electron systems with low levels of disorder is determined using the spin-polarization dependence ...
