| contents | We theoretically investigate the impact of weak static perturbations of a flat potential on the density of a quasi-two-dimensional dipolar Bose gas. {We consider the perturbative effects of potential perturbations at first order and restrict to the mean-field stable regime. We first study cosinusoidal potential perturbations at a given spatial frequency; this allows us to understand the effects of optical lattices as well as of isolated momentum contributions in the Fourier decomposition of an arbitrary potential. We then study potential perturbations characterized by a static white-noise spectrum over a given momentum range; this captures the effects of inherent optical aberrations in setups that create uniform optical dipole traps. |
