Magnetic phases of one-dimensional lattices with 2-4 fermions per site
(2008) In New Journal of Physics 10. p.14-063013- Abstract
- We study the spectral and magnetic properties of one-dimensional lattices filled with 2-4 fermions (with spin-1/2) per lattice site. We use a generalized Hubbard model that takes into account all the interactions on a lattice site, and solve the many-particle problem by exact diagonalization. We find an intriguing magnetic phase diagram which includes ferromagnetism, spin-1 Heisenberg antiferromagnetism and orbital antiferromagnetism.
