“…Unlike the above mentioned computationally complex techniques that yield more accurate results, the IDGMF method ignore the details of correlation, and its computational simplicity is the main advantage, thus making it as the common method for the BH model. Moreover, apart from the ground-state phases, the dynamical transitions and thermalization effects at finite temperature [35,98,99] are also can be obtained using this Gutzwiller approach.…”

We investigate the quantum phases and phase transitions forspin-orbit coupled two-species bosons with nearest-neighbor (NN)interaction in a two-dimensional square lattice usinginhomogeneous dynamical Guztwiller mean-field (IDGMF) method.Under the effect of spin-orbit coupling (SOC) and NN interaction,we uncover a rich variety of different magnetic supersolid (SS)phases. In the presence of intraspecies NN interaction, the phasediagram exhibits the phase-twisted double-checkerboard SS(PT-DCSS) and phase-striped double-checkerboard SS (PS-DCSS)phases. For both intra- and interspecies NN interactions, apartfrom the phase-twisted lattice SS (PT-LSS) and phase-stripedlattice SS (PS-LSS) phases, some nontrivial SS phases withinteresting properties occur. More importantly, we find that theemergences of these nontrivial SS phases are dependent of theinterspecies on-site interaction. To further characterize the SSphases, we also discuss the spin-dependent momentum distributionsand magnetic textures. The magnetic textures, such asantiferromagnetic, spiral and stripe orders are shown. Finally, wegive the fully analytical insights into the numerical results.
