1. On the Properties of Some Strongly Correlated Systems - Analytical and Numerical Studies
Abstract : This thesis is dedicated to analytical and numerical studiesof a few models of strongly correlated systems and thedevelopment of techniques for such studies. The common name"strongly correlated" refers to systems in which theinteractions (correlations) between the constituent particleslead to nontrivial properties, such as various types ofmagnetism, superconductivity, and exotic phases.

2. Non-Orthogonality and Electron Correlations in Nanotransport : Spin- and Time-Dependent Currents
Abstract : The concept of the transfer Hamiltonian formalism has been reconsidered and generalized to include the non-orthogonality between the electron states in an interacting region, e.g. quantum dot (QD), and the states in the conduction bands in the attached contacts. READ MORE

3. Theory of Electron Transport in Superconducting Heterostructures
Abstract : This thesis deals theoretically with electron transport in superconducting heterostructures. Depending on the system I use different theoretical approaches. The thesis contains an introduction followed by four research papers (Papers I-IV). The introduction gives the background of the work in Papers I-IV. READ MORE
