General information about the project

The rapid progress in miniaturization of electronic devices inevitably brings the current technology closer to a certain natural limit, when the manipulation of individual molecules, atoms or spins will constitute the basis for processing and storing information. Regardless of how distant this perspective seems to be, comprehensive understanding of physics at the nanoscale will certainly be of vital importance. The theoretical studies of transport properties of nanoscale systems, such as molecules, quantum dots or nanowires, due to strong electron correlations, are very demanding and the methods used are very often based on a series of approximations. Consequently, there are relatively few results that can be considered as benchmarks, and which can be directly compared to experiments. The aim of this project is to provide very accurate results and new predictions for problems that have not been studied yet. One of such open problems is undoubtedly the accurate quantitative calculation of transport characteristics in non-equilibrium conditions and the determination of dynamics with exact treatment of correlations. Therefore, the main goal of this project is to develop and adapt advanced numerical methods based on renormalization group techniques to study transport properties of correlated nanoscale systems, with particular emphasis on non-equilibrium and dynamical phenomena.
