Bosonization of dimerized spinless-fermion and Hubbard chains
Carmen Mocanu
The low energy properties of different one-dimensional fermionic lattice models are investigated using the bosonization technique. We attach much importance to a proper considerati…
The Peierls-Hubbard model at weak coupling
Michael Dzierzawa, Carmen Mocanu
We investigate the Peierls transition in the one-dimensional Peierls-Hubbard model at half filling in the adiabatic approximation for the lattice. Depending on the value of the ele…
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…
