Cayley transform applied to non-interacting quantum transport
Horia D. Cornean, Hagen Neidhardt, Lukas Wilhelm +1
We extend the Landauer-Büttiker formalism in order to accommodate both unitary and self-adjoint operators which are not bounded from below. We also prove that the pure point and si…
Optical Hall conductivity in bulk and nanostructured graphene beyond the Dirac approximation
Jesper Goor Pedersen, Mikkel H. Brynildsen, Horia D. Cornean +1
We present a perturbative method for calculating the optical Hall conductivity in a tight-binding framework based on the Kubo formalism. The method involves diagonalization only of…
Memory effects in non-interacting mesoscopic transport
Horia D. Cornean, Arne Jensen, Gheorghe Nenciu
Consider a quantum dot coupled to two semi-infinite one-dimensional leads at thermal equilibrium. We turn on adiabatically a bias between the leads such that there exists exactly o…
On the regularity of the Hausdorff distance between spectra of perturbed magnetic Hamiltonians
Horia D. Cornean, Radu Purice
We study the regularity properties of the Hausdorff distance between spectra of continuous Harper-like operators. As a special case we obtain Hölder continuity of this Hausdorff di…
MIMO capacity for deterministic channel models: sublinear growth
Francois Bentosela, Horia D. Cornean, Nicola Marchetti
This is the second paper of the authors in a series concerned with the development of a deterministic model for the transfer matrix of a MIMO system. Starting from the Maxwell equa…
