Magnetism of quantum dot clusters: A Hubbard model study
J. -P. Nikkarila, M. Koskinen, M. Manninen
Magnetic properties of two and three-dimensional clusters of quantum dots are studied with exact diagonalization of a generalized Hubbard model. We study the weak coupling limit, w…

Magnetic phases of one-dimensional lattices with 2 to 4 fermions per site
J. -P. Nikkarila, M. Koskinen, S. M. Reimann +1
We study the spectral and magnetic properties of one-dimensional lattices filled with 2 to 4 fermions (with spin 1/2) per lattice site. We use a generalized Hubbard model that take…
