In this paper we demonstrate a new type of quantum phase coherence QPC , which is generated by the two-body interaction. This conclusion is based on quantum master equation analysis for the full counting statistics of electron transport through two parallel quantum-dots with antiparallel magnetic fluxes in order to eliminate the Aharonov-Bohm interference of either single-particle or non-interacting two-particle wave functions.

This book introduces researchers and students to the physical principles which govern the operation of solid-state devices whose overall length is smaller than the electron mean free path. In such quantum systems, electron wave behavior prevails, and transport properties must be assessed by calculating transmission amplitudes rather than microscopic conductivity. Emphasis is placed on detailing the physical laws that apply under these circumstances, and on giving a clear account of the most important phenomena. The coverage is comprehensive, with mathematics and theoretical material systematically kept at the most accessible level. The various physical effects are clearly differentiated, ranging from transmission formalism to the Coulomb blockade effect and current noise fluctuations. Some Useful Concepts and Reminders.

In mesoscopic physics , ballistic conduction ballistic transport is the unimpeded flow or transport of charge carriers usually electrons , or energy-carrying particles, over relatively long distances in a material. Without scattering, electrons simply obey Newton's second law of motion at non-relativistic speeds. The mean free path of a particle can be described as the average length that the particle can travel freely, i. The mean free path can be increased by reducing the number of impurities in a crystal or by lowering its temperature. Ballistic transport is observed when the mean free path of the particle is much longer than the dimension of the medium through which the particle travels.

What can we learn from noise? — Mesoscopic nonequilibrium statistical physics —

The book discusses nanostructure physics; nanostructures in motion; and advances in nanostructure fabrication. The text also describes ballistic transport and coherence; low-dimensional tunneling; and electron correlation and coulomb blockade. Banostructure arrays and collective effects; the theory and modeling of nanostructures; and mesoscopic systems are also encompassed. The book further tackles the optical properties of nanostructures. We are always looking for ways to improve customer experience on Elsevier.

Electronic transport in mesoscopic systems pdf Electronic transport in mesoscopic systems pdf. After an initial chapter covering fundamental concepts, the transmission function formalism is presented, and used to describe three key topics in mesoscopic physics: the quantum Hall effect; localisation; and double-barrier tunnelling. Fluctuations are significant in mesoscopic systems and of particular importance in understanding quantum transport.

Mesoscopic systems — small electric circuits working in quantum regime — offer us a unique experimental stage to explorer quantum transport in a tunable and precise way. The purpose of this Review is to show how they can contribute to statistical physics. We introduce the significance of fluctuation, or equivalently noise, as noise measurement enables us to address the fundamental aspects of a physical system. The significance of the fluctuation theorem FT in statistical physics is noted. We explain what information can be deduced from the current noise measurement in mesoscopic systems.

Electronic Quantum Transport in Mesoscopic Semiconductor Structures

Стратмор покачал головой: - Танкадо дал нам шанс. Это совершенно ясно. Тем не менее риск велик: если нас обнаружат, это, в сущности, будет означать, что он своим алгоритмом нас напугал.

This article examines spin currents and spin densities in realistic open semiconductor nanostructures using different tools of quantum-transport theory based on the non-equilibrium Green function NEGF approach.

This book treats three topics of electronic quantum transport in mesoscopic semiconductor structures: the conductance in strongly interacting and disordered two-dimensional systems and the metal insulator transition, electron transport through quantum dots and quantum rings in the Coulomb-blockade regime, and scanning probe experiments on semiconductor nanostructures at cryogenic temperatures.
