Strongly Spinor Ferromagnetic Bose Gases (1604.01163v4)
Published 5 Apr 2016 in cond-mat.quant-gas
Abstract: By studying the zero-temperature and nonzero-temperature phase diagrams of the ferromagnetic spin-1 Bose-Hubbard model under an external magnetic field, we find that the competition between ferromagnetism and the quadratic Zeeman energy yields two superfluid phases, which feature discontinuous first-order phase transitions between them for a strongly spinor Bose gas such as ${}7$Li, contrary to the corresponding continuum system.
