Interaction correction to the conductance of a ballistic conductor
Piet W. Brouwer, Joern N. Kupferschmidt
In disordered metals, electron-electron interactions are the origin of a small correction to the conductivity, the "Altshuler-Aronov correction". Here we investigate the Altshuler-…
Demonstration of one-parameter scaling at the Dirac point in graphene
J. H. Bardarson, J. Tworzydło, P. W. Brouwer +1
We numerically calculate the conductivity of an undoped graphene sheet (size ) in the limit of vanishingly small lattice constant. We demonstrate one-parameter scaling for r…
Semiclassical theory of the Ehrenfest-time dependence of quantum transport
Piet W. Brouwer
In ballistic conductors, there is a low-time threshold for the appearance of quantum effects in transport coefficients. This low-time threshold is the Ehrenfest time. Most previous…
Universal parametric correlations in the classical limit of quantum transport
Piet W. Brouwer, Saar Rahav
Quantum corrections to transport through a chaotic ballistic cavity are known to be universal. The universality not only applies to the magnitude of quantum corrections, but also t…
