Insulator-superfluid transition of spin-1 bosons in an optical lattice in magnetic field Academic Article

abstract

• The phase transition of spin-1 bosons in the presence of an external magnetic field was studied. Magnetic field lifts a degeneracy of the antiferromagnetic ground state and enriches the phase diagram. It was shown that magnetic field results in a qualitatively different effect. Depending on the field value, the transition for bosons with antiferromagnetic interparticle interaction may occur into different polar superfluid phases with spins aligned along or opposite to the field direction.
