Field-induced phase transitions of repulsive spin-1 bosons in optical lattices
K. Rodriguez, A. Argüelles, A. K. Kolezhuk +2
We study the phase diagram of repulsively interacting spin-1 bosons in optical lattices at unit filling, showing that an externally induced quadratic Zeeman effect may lead to a ri…

Magnetic phases of spin-3/2 fermions on a spatially anisotropic square lattice
A. K. Kolezhuk, T. Vekua
We study the magnetic phase diagram of spin-3/2 fermions in a spatially anisotropic square optical lattice at quarter filling (corresponding to one particle per lattice site). In t…
