Journal ArticleDOI
Metal–insulator transition in a weakly interacting many-electron system with localized single-particle states
TL;DR: In this paper, it was shown that in the absence of coupling of the electrons to any external bath dc electrical conductivity exactly vanishes as long as the temperature T does not exceed some finite value Tc.
Journal ArticleDOI
The focusing of electron flow and a Veselago lens in graphene p-n junctions.
TL;DR: The focusing of electric current by a single p-n junction in graphene is theoretically predicted and may be useful for the engineering of electronic lenses and focused beam splitters using gate-controlled n-p-n junctions in graphene-based transistors.
Journal ArticleDOI
Weak-localization magnetoresistance and valley symmetry in graphene.
Edward McCann,Kostyantyn Kechedzhi,Vladimir I. Fal'ko,Hidekatsu Suzuura,Tsuneya Ando,Boris L. Altshuler +5 more
TL;DR: This work evaluates the dependence of the magnetoresistance of graphene on relaxation rates associated with various possible ways of breaking a "hidden" valley symmetry of the system by evaluating the dependent rates of trigonal warping and intervalley scattering.
Journal ArticleDOI
Interaction Effects in Disordered Fermi Systems in Two Dimensions
TL;DR: In this paper, the interaction effects in disordered Fermi systems are considered in the metallic regime, and logarithmic corrections are obtained for conductivity, density of states, specific heat, and Hall constant.
Journal ArticleDOI
1 / f noise: Implications for solid-state quantum information
TL;DR: In this paper, a review of the current state of the theory of decoherence due to degrees of freedom producing 1/f noise is presented, and several strategies for minimizing the noise-induced phase coherence are discussed.
