When creating a model of composite medium based on carbon nanotubes in the gigahertz and subterahertz ranges, it is necessary to take into account tunnel coupling between nanoparticles. To simplify consideration, we present consisting same randomly oriented linear chains parallel single walled metallic connected by contacts. The problem scattering electromagnetic radiation was solved through ap...

We introduce a fast and highly efficient physically realizable bit swap. Employing readily available scalable Josephson junction microtechnology, the design implements recently introduced paradigm of momentum computing. Its nanosecond speeds sub-Landauer thermodynamic efficiency arise from dynamically storing memory in degrees freedom. As such, during swap, microstate distribution is never near...

Abstract Realizing the promises of molecular electronic devices requires an understanding transport on nanoscale. Here, we consider a Su-Schrieffer-Heeger model for semi-conducting trans-polyacetylene wires in which endow charge carriers with finite lifetime. The aim this exercise is two-fold: (i) simplicity allows insightful numerical and analytical comparison Landauer Kubo linear-response for...

We describe microscopic theory for the quantum transport through finite interacting systems connected to noninteracting leads. It can be applied to small systems such as quantum dots, quantum wires, atomic chain, molecule, and so forth. The Keldysh formalism is introduced to study the nonlinear current-voltage characteristics, and general properties of the nonequilibrium Green’s functions are p...
