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…

Friedel transition in a modified XY model
M. Dzierzawa, M. Zamora, D. Baeriswyl +1
Weakly coupled superconducting layers are described by the three-dimensional XY model with strong coupling in two directions and weak coupling in the third direction. For the usual…
