Query: Interacting spin-orbit-coupled spin-1 Bose-Einstein condensates   The recent experimental realization of spin-orbit (SO) coupling for spin-1
ultracold atoms opens an interesting avenue for exploring SO-coupling-related
physics in large-spin systems, which is generally unattainable in electronic
materials. In this paper, we study the effects of interactions between atoms on
the ground states and collective excitations of SO-coupled spin-1 Bose-Einstein
condensates (BECs) in the presence of a spin-tensor potential. We find that
ferromagnetic interaction between atoms can induce a stripe phase exhibiting
in-phase or out-of-phase modulating patterns between spin-tensor and
zero-spin-component density waves. We characterize the phase transitions
between different phases using the spin-tensor density as well as the
collective dipole motion of the BEC. We show that there exists a double
maxon-roton structure in the Bogoliubov-excitation spectrum, attributed to the
three band minima of the SO-coupled spin-1 BEC.
