Multi-color Fermi-liquid theory of quantum transport through a multilevel Kondo impurity

The work presented in this thesis mainly focuses on the development of theoretical framework to describe the non-equilibrium transport through nano-sized quantum devices in the presence of strong electron-electron interactions and resonance scattering. The main objective of this research is to further understand the exotic transport processes in the non-equilibrium setup of a nanoscale system. The collection of findings presented in this thesis could be useful in the development of very efficient thermoelectric devices, quantum computation and information processing, and significantly improve the understanding of the many-body physics associated with the stronglycorrelated electronic systems. In addition, the domain of applicability of the presented ideas and theoretical formulation are quite broad, not limited to the systems studied in this thesis.
