Hubbard ladders in a magnetic field
D. C. Cabra, A. De Martino, P. Pujol +1
The behavior of a two leg Hubbard ladder in the presence of a magnetic field is studied by means of Abelian bosonization. We predict the appearance of a new (doping dependent) plat…
Emergence of Irrationality: Magnetization Plateaux in Modulated Hubbard Chains
D. C. Cabra, A. De Martino, A. Honecker +2
Hubbard chains with periodically modulated coupling constants in a magnetic field exhibit gaps at zero temperature in their magnetic and charge excitations in a variety of situatio…
Random bond XXZ chains with modulated couplings
D. C. Cabra, A. De Martino, M. D. Grynberg +2
The magnetization behavior of q-periodic antiferromagnetic spin 1/2 Heisenberg chains under uniform magnetic fields is investigated in a background of disorder exchange distributio…
