Abstract

We study the effects of the intertube dipole-dipole interactions (DDIs) in recent experiments with arrays of nearly integrable one-dimensional (1D) dipolar Bose gases of ${}^{162}{Dy}$ atoms. An earlier theoretical modeling ignored those interactions, which we include here via a modification of the 1D confining potentials. We investigate the effects of the intertube DDIs both during the state preparation and during the measurements of the rapidity distributions. We explore how the strength of the contact interactions and the magnetic-field angles modify the intertube DDI corrections. We find that those corrections slightly change both the properties of the equilibrium state and the rapidity measurements. Remarkably, however, the changes nearly cancel each other, resulting in measured rapidity distributions that are very close to those predicted in the absence of the intertube DDIs.
