R-matrix formalism for electron scattering in two dimensions
P. N. Racec, E. R. Racec, H. Neidhardt
We investigate the scattering phenomena in two dimensions produced by a general finite-range nonseparable potential. This situation can appear either in a Cartesian geometry or in…
Evanescent channels and scattering in cylindrical nanowire heterostructures
P. N. Racec, E. R. Racec, H. Neidhardt
We investigate the scattering phenomena produced by a general finite-range nonseparable potential in a multi-channel two-probe cylindrical nanowire heterostructure. The multi-chann…
On Eisenbud's and Wigner's R-matrix: A general approach
J. Behrndt, H. Neidhardt, E. R. Racec +2
The main objective of this paper is to give a rigorous treatment of Wigner's and Eisenbud's -matrix method for scattering matrices of scattering systems consisting of two selfad…
Admittance of planar two-terminal quantum systems
U. Wulf, P. N. Racec, E. R. Racec
We develop an approach to calculate the admittance of effectively one-dimensional open quantum systems in random phase approximation. The stationary, unperturbed system is describe…
Resonant transport throught semiconductor nanostructures
E. R. Racec, P. N. Racec, U. Wulf
Transport through semiconductor nanostructures is a quantum-coherent process. This paper focuses on systems in which the electron's dynamics is ballistic and the transport is domin…
