Incompleteness of the Landauer formula for electronic transport
We show that the Landauer formula for the conductance of a nanoscale system is incomplete because it does not take into account many-body effects which cannot be treated as contributions to the single-particle transmission probabilities. We show that the physical origin of these effects is related to the viscous nature of the electron liquid and we develop a perturbative formalism, based on the...
متن کاملNon-equilibrium Landauer transport model for Hawking radiation from a black hole
We propose that the Hawking radiation energy and entropy flow rates from a black hole can be viewed as a one-dimensional (1D), nonequilibrium Landauer transport process. Support for this viewpoint comes from previous calculations invoking conformal symmetry in the near-horizon region, which give radiation rates that are identical to those of a single 1D quantum channel connected to a thermal re...
متن کاملQuantum Mechanical Aspects of Transport in Nanoelectronics
Innovations in semiconductor technology have provided us with an opportunity to examine devices with vertical and lateral dimensions less than 100 nm-comparable to the wavelength of the electron at the Fermi energy. At low temperature, the confinement and the coherence of the electronic motion on the scale of the electron wavelength give rise to gross deviations from classical charge transport ...
متن کاملWaiting for Landauer
Landauer’s Principle asserts that there is an unavoidable cost in thermodynamic entropy creation when data is erased. It is usually derived from incorrect assumptions, most notably, that erasure must compress the phase space of a memory device or that thermodynamic entropy arises from the probabilistic uncertainty of random data. Recent work seeks to prove Landauer’s Principle without using the...
متن کاملUsing Generalized Language Model for Question Matching
Question and answering service is one of the popular services in the World Wide Web. The main goal of these services is to finding the best answer for user's input question as quick as possible. In order to achieve this aim, most of these use new techniques foe question matching. . We have a lot of question and answering services in Persian web, so it seems that developing a question matching m...
