Markovian Approximations to the Time Evolution of Lead Coupled Spinless Hubbard Chains through Different Master Equation Approaches

This thesis describes the process of deriving the Master Equation for the time evolution of the density operator for a lead coupled spinless Hubbard chain using a Markov approximation. The derivation is done in a direct, conventional way of expanding operators and switching pictures in order to separate the system Hamiltonian in a convenient way...
