Landauer conductance and twisted boundary conditions for Dirac fermions in two space dimensions
Landauer conductance and twisted boundary conditions for Dirac fermions in two space dimensions
We apply the generating function technique developed by Nazarov to the computation of the density of transmission eigenvalues for a two-dimensional free massless Dirac fermion, which, e.g., underlies theoretical descriptions of graphene. By modeling ideal leads attached to the sample as a conformal invariant boundary condition, we relate the generating …
