Tīmeklis2024. gada 21. okt. · Abstract. Charge transport through molecular junctions is often described either as a purely coherent or a purely classical phenomenon, and described using the Landauer-Büttiker formalism or Marcus theory (MT), respectively. Using a generalised quantum master equation, we here derive an expression for current … TīmeklisAbstract. We give a short presentation of two recent results. The first one is a rigorous proof of the Landauer-Büttiker formula, and the second one concerns resonant quantum transport. The detailed results are in [2]. In the last section we present the results of some numerical computations on a model system.

The Landauer-Büttiker formula and resonant quantum transport

TīmeklisThe elegance of the Landau-Buttiker formalism is due to this simple fundamental result. In the above discussion we use a particular gauge to make the treatment transparent. However, the essential results are all gauge invariant. Thus, suppose that we change to a new gauge in which the vector potential becomes A = A + Vx. Then qek is replaced Tīmeklis2002. gada 15. aug. · The applications include traditional transport theory in bulk as well as mesoscopic systems, where both the Landau-Buttiker formalism and recent developments in correlated transport phenomena in mesoscopic systems and nano-structures are covered. Other topics include interacting electron gases, plasmons, … TīmeklisReverse computing has been found to provide more efficient forms of computation. Reverse computing means computation that takes place in steps that are time reversible. If a reversible computation yields a series of outputs, then the inverse computation on these outputs should reproduce the original states [3]. dsm acute psychosis
