Bosonization of dimerized Hubbard chains
C. Mocanu, M. Dzierzawa, P. Schwab +1
The role of Klein factors is investigated for the bosonized Hamiltonian of the dimerized Hubbard model. Contrary to previous approaches we take into account their number changing p…
Finite-Size Bosonization and Self-Consistent Harmonic Approximation
C. Mocanu, M. Dzierzawa, P. Schwab +1
The self-consistent harmonic approximation is extended in order to account for the existence of Klein factors in bosonized Hamiltonians. This is important for the study of finite s…
Spin-Hall effect in a disordered 2D electron-system
Roberto Raimondi, Peter Schwab
We calculate the spin-Hall conductivity for a two-dimensional electron gas within the self-consistent Born approximation, varying the strength and type of disorder. In the weak dis…
Electronic thermal conductivity of disordered metals
Roberto Raimondi, Giorgio Savona, Peter Schwab +1
We calculate the thermal conductivity of interacting electrons in disordered metals. In our analysis we point out that the interaction affects thermal transport through two distinc…
