This paper reviews several applications of photonic side-bands, used by Büttiker and Landauer in their theory of traversal time in tunneling [Phys. Rev. Lett. 49, 1739 (1982)], in transport and optics of mesoscopic systems. Topics include generalizations of the transmission theory of transport to time-dependent situations, optics and transport of mesoscopic systems in THz electromagnetic fields...

Persistent currents in mesoscopic cavities and the effect of level crossings as random variables Abstract In the present article we perform analytical and numerical calculations related to persistent currents in 2D isolated mesoscopic annular cavities threaded by a magnetic flux. The system considered has a high number of open channels and therefore the single particle spectrum exhibits many le...

The feeling of the reaching of a crucial turning point is shared by the whole spectrum of sciences. The main features of this turning point are basically identical across different disciplines and can be interpreted as a re-location of the most relevant level of explanation (and consequently intervention for more applicative fields) from the microscopic to the so called mesoscopic level. Here, ...

Dissipative particle dynamics (DPD) is now a well-established method for simulating soft matter systems. However, its applicability was recently questioned because some investigations showed an upper coarse-graining limit that would prevent the applicability of the method to the whole mesoscopic range. This article aims to re-establish DPD as a truly mesoscopic method by analyzing the problems ...

Double-well optical lattice in an insulating state is considered. The influence of atomic vibrations and mesoscopic disorder on the properties of the lattice are studied. Vibrations lead to the renormalization of atomic interactions. The occurrence of mesoscopic disorder results in the appearance of first-order phase transitions between the states with different levels of atomic imbalance. The ...

We investigate spin-dependent transport in multiterminal mesoscopic cavities with spin-orbit coupling. Focusing on a three-terminal set-up we show how injecting a pure spin current or a polarized current from one terminal generates additional charge current and/or voltage across the two output terminals. When the injected current is a pure spin current, a single measurement allows us to extract...
