Exact ground states of extended t-J_{z} models on a square lattice
Zohar Nussinov, Anders Rosengren
We examine special extended spin S=1/2 fermionic and hard core bosonic t-J_{z} models and find exact ground states. Some of these models display an exponentially large degeneracy w…

Phase Diagram of the 1D Kondo Lattice Model
I. P. McCulloch, M. Gulacsi, S. Caprara +1
We determine the boundary of the fully polarized ferromagnetic ground state in the one dimensional Kondo lattice model at partial conduction electron band filling by using a newly…

Critical properties and phase diagram of the quantum anisotropic XY spin chain in a random magnetic field: A density-matrix renormalization-group analysis
A. Juozapavicius, L. Urba, S. Caprara +1
The spin-1/2 quantum anisotropic XY spin chain in a transverse random magnetic field parallel to the z axis is numerically studied by means of the density-matrix renormalization gr…
