We propose a method to determine the relative strength of Rashba and Dresselhaus spin-orbit interaction from transport measurements without the need of fitting parameters. To this end, we make use of the conductance anisotropy in narrow quantum wires with respect to the directions of an in-plane magnetic field, the quantum wire, and the crystal orientation. We support our proposal by numerical ...

Theory and experiment examining electron transfer through molecules bound to electrodes are increasingly focused on quantities that are conceptually far removed from current chemical understanding. This presents challenges both for the design of interesting molecules for these devices and for the interpretation of experimental data by traditional chemical mechanisms. Here, the concept of electr...

The implementation of a source to drain tunneling in ultrascaled devices using MS-EMC has traditionally led overestimated current levels the subthreshold regime. In order correct this issue and enhance capabilities type simulator, we discuss paper two alternative self-consistent solutions focusing on different parts simulation flow. first solution reformulates probability computation by modulat...

We develop a Landauer-Büttiker theory of entropy evolution in time-dependent, strongly coupled electron systems. The formalism naturally avoids the problem of the system-bath distinction by defining the entropy current in the attached leads. This current can then be used to infer changes of the entropy of the system which we refer to as the inside-outside duality. We carry out this program in a...

The effect of a ferromagnetic scanning tunneling microscope (STM) cobalt tip on the electronic, magnetic and electronic transport properties Co-phthalocyanine (CoPc)/Co(111) junction has been investigated in framework density functional theory conjunction with Landauer non-equilibrium Green function formalism. It is shown that spin moment CoPc molecule can be flipped by varying distance between...

We consider the ballistic transport of quasiparticles with exclusion statistics through a 1D wire within the Landauer-Büttiker approach. We demonstrate that quasiparticle transport coefficients (electrical and heat conductance, as well as thermopower) are determined by the same general formulae as for particles with normal statistics. By applying the developed formalism to the ballistic transpo...

Maxwell’s Demon, ‘a being whose faculties are so sharpened that he can follow every molecule in its course’, has been the centre of much debate about its abilities to violate the second law of thermodynamics. Landauer’s hypothesis, that the Demon must erase its memory and incur a thermodynamic cost, has become the standard response to Maxwell’s dilemma, and its implications for the thermodynami...
