Finite difference method for transport properties of massless Dirac fermions
J. Tworzydlo, C. W. Groth, C. W. J. Beenakker
We adapt a finite difference method of solution of the two-dimensional massless Dirac equation, developed in the context of lattice gauge theory, to the calculation of electrical c…
Electronic shot noise in fractal conductors
C. W. Groth, J. Tworzydlo, C. W. J. Beenakker
By solving a master equation in the Sierpinski lattice and in a planar random-resistor network, we determine the scaling with size L of the shot noise power P due to elastic scatte…
Calculation of the conductance of a graphene sheet using the Chalker-Coddington network model
I. Snyman, J. Tworzydlo, C. W. J. Beenakker
The Chalker-Coddington network model (introduced originally as a model for percolation in the quantum Hall effect) is known to map onto the two-dimensional Dirac equation. Here we…
