Abstract
Motivated by the recent experimental observation of dipolar supersolid stripes in a quasi-two-dimensional geometry [arXiv:2512.13280], we study a trapped system of fully polarized dipoles in a strongly axially confined geometry, at both zero and finite temperatures, by means of Bogoliubov theory. The dipoles are strongly harmonically trapped along the axis and subjected to a box trap in the plane. We characterize the physics of the trapped system at zero and finite temperatures as a function of the tilting angle of the dipoles, the number of particles, and the scattering length, restricting ourselves to the experimentally relevant regime of large condensate fractions. We also illustrate the influence of the aspect ratio of the box trap in the liquid character of the system and its structure. We observe a remarkable promotion of spatial modulations when temperature is increased while keeping the total particle number constant for specific configurations, in qualitative agreement with previous Monte Carlo results in a three-dimensional geometry. Our results are useful to understand the zero-temperature physics of the trapped dipolar system in the quasi-two-dimensional limit and in the strongly dipolar regime. In addition, they allow us to assess the effect of temperature in its equilibrium properties in experimentally relevant conditions, which may be useful for thermometry applications.
