The magnetoresistance of a one-dimensional electron gas in a metallic ferromagnetic nanowire containing two atomic-size domain walls has been investigated in the presence of spin-orbit interaction. The magnetoresistance is calculated in the ballistic regime, within the Landauer-Büttiker formalism. It has been demonstrated that the conductance of a magnetic nanowire with double domain walls...

Disordered T-shaped graphene nanodevice (TGN) was designed and studied in this paper. We demonstrated the intrinsic transport properties of the TGN by using Landauer approach. Knowing the transmission probability of an electron the current through the system is obtained using Landauer-Buttiker formalism. The effects of single disorder on conductance, current and on the transport length scales a...

Electron transport across molecular junctions is a rapidly growing topic at the borderline between physics and chemistry. We review calculations which were done in the Landauer transport formalism for monovalent systems, ranging from clusters to fullerenes. A realistic description of molecular conductance can be achieved by a density functional based approach to the calculation of the electroni...

We illustrate how classical chaotic dynamics influences the quantum properties at mesoscopic scales. As a model case we study semiclassically coherent transport through ballistic mesoscopic systems within the Landauer formalism beyond the so-called diagonal approximation, i.e. by incorporating classical action correlations. In this context we review and explain the two main trajectory-based met...

This document describes the use of the electronic transport functionality that is implemented in the ONETEP code[1]. The implementation computes the ballistic Landauer-Büttiker conductance at zero bias through a device and associated properties using electronic structure derived from density functional theory (DFT). The calculation proceeds as a post-processing step after a ground-state single-...

We study the quantum transport through networks of diffusive wires connected to reservoirs in the Landauer-Büttiker formalism. The elements of the conductance matrix are computed by the diagrammatic method. We recover the combination of classical resistances and obtain the weak localization corrections. For arbitrary networks, we show how the Cooperon must be properly weighted over the differen...
