In the case of spin-dependent hopping we have presented arguments <strong>for</strong> the neglegt ofCDW phases. In order to complete this argument, a proof that this phase is thermodynamicallyunstable away from half filling could be added.In the future, multiband <strong>Hubbard</strong> models and dissipative multiband <strong>Hubbard</strong> modelscould become realizable in ultracold quantum gases, and there<strong>for</strong>e methods like DMFT+QMC+ 1 ω[27] could be used to analyze these systems.58
