Competing effects of interactions and spin-orbit coupling in a quantum wire
V. Gritsev, G. I. Japaridze, M. Pletyukhov +1
We study the interplay of electron-electron interactions and Rashba spin-orbit coupling in one-dimensional ballistic wires. Using the renormalization group approach we construct th…

Effective Hamiltonian for a Half-filled Hubbard Chain with Alternating On-site Interactions
Paata Kakashvili, George I. Japaridze
We derive an effective spin Hamiltonian for the one-dimensional half-filled Alternating Hubbard model in the limit of strong on-site repulsion. We show that the effective Hamiltoni…

Phase diagram and optical conductivity of the ionic Hubbard model
P. Brune, G. I. Japaridze, A. P. Kampf +1
We investigate the ground state phase diagram of the one-dimensional ionic Hubbard model with an alternating potential at half-filling by the bosonization technique as well as by n…
