Summary: We study a gas of bosonic dipolar atoms in the presence of a transverse harmonic trapping potential by using an improved variational Bethe ansatz, which includes the transverse width of the atomic cloud as a variational parameter. Our calculations show that the system behavior evolves from quasi-one dimensional to a strictly one-dimensional one by changing the atom-atom interaction, or the axial density, or the frequency of the transverse confinement. Quite remarkably, in the droplet phase induced by the attractive dipolar interaction the system becomes sub-one dimensional when the transverse width is smaller than the characteristic length of the transverse harmonic confinement.

Summary: We study the application of a square perturbing lattice to hexagonal arrays of dipolar droplets in a dipolar Bose-Einstein condensate. The application of the lattice causes spontaneous pattern formation and frustration in some regimes. The ground state does not have the symmetry of either the intrinsic hexagonal supersolid or the square lattice for certain parameters.

Summary: We calculate the ground states of a dipolar Bose gas confined in an infinite tube potential using the extended Gross-Pitaevskii equation theory and a numerical method. The method includes an analytic result for a truncated dipole-dipole interaction potential, allowing accurate evaluation of long-ranged interactions within a unit cell. Our focus is on the transition of the ground state to a crystal driven by dipole-dipole interactions. The transition is found to be continuous or discontinuous depending on the average system density, providing insight into the supersolid phase transition observed in recent experiments.

Summary: In this study, we investigate the nonlocal GP equation with long-range dipole-dipole and contact interactions. Analytical and numerical results show that trapless dipolar BECs remain stable not only for the usual combination of attractive binary and repulsive three-body interactions, but also for the case when these terms have opposite signs. The stability of the dipolar BECs can be further improved by time-periodic modulation of the three-body interaction imposed by means of Feshbach resonance.

Summary: This study investigates the effect of beyond-mean-field quantum-fluctuation (QF) Lee-Huang-Yang (LHY) and three-body interactions on the formation of dipolar Bose-Einstein condensate (BEC) droplets. The size, shape, and energy of polarized 164Dy atom dipolar droplets are obtained using numerical and variational approximation methods.

Summary: Angular oscillations can serve as a useful probe for superfluid properties, but in systems with 2D structure, the frequency of angular oscillations remains nearly unchanged even with significant alterations in superfluidity, suggesting that they may not always provide a robust experimental probe for superfluidity with typical experimental protocols.

Summary: In this paper, a model is used to demonstrate the crystallization of droplets in a polarized dipolar condensate in a three-dimensional trap. The droplet lattice is formed in a clean and distortion-free manner in the box traps, allowing for experimental observation of the droplet lattice with a reduced number of atoms compared to a harmonic trap.

Summary: Gases of doubly dipolar particles, with both magnetic and electric dipole moments, offer intriguing novel possibilities. The interplay between doubly dipolar interactions, quantum stabilization, and external confinement results in a rich ground-state physics of supersolids and incoherent droplet arrays in doubly dipolar condensates. Our study reveals novel possibilities for engineering quantum droplets and droplet supersolids, including supersolid-supersolid transitions and the realization of supersolid arrays of pancake droplets.

Summary: We investigate the density distributions of a dipolar Bose-Einstein condensed gas confined in a box potential, focusing on the effects of supersolidity. The ground-state density exhibits a depletion in the bulk region and an accumulation of atoms near the walls due to the competition between attractive and repulsive forces. In a quasi-two-dimensional geometry, we observe a ringlike configuration near the boundary of the box, indicating supersolid and crystal effects. In the case of square box trapping, density oscillations along the edges resemble quasi-one-dimensional configurations. Supersolidity can also be observed in the bulk region for large atom numbers, reflecting the symmetry of the confining potential.

Summary: The study focuses on Bose-Einstein condensates in bubble trap potentials under small gravity, particularly examining thin shells with contact and dipolar interactions. Analysis is conducted on the effects of anisotropic dipolar interactions, as well as investigating the dynamics of small oscillations triggered by tilting or changing the gravity direction in a small gravity context. This system could serve as a preliminary stage for a gravity sensor in space laboratories.

Summary: Through theoretical investigation, we found that spontaneous rotational symmetry breaking can lead to the emergence of a supersolid phase with characteristic collective excitations in specific regimes. Studying the dynamics across the transition, we demonstrate how these supersolids can be realized using standard protocols in state-of-the-art experiments.

Summary: In this study, we investigate theoretically the supersolidity in three-dimensional dipolar Bose-Einstein condensates, focusing on the impact of trap geometry on the dimensionality of resulting droplet arrays. We found that supersolidity is well established in one-dimensional arrays and may also be favorable in two-dimensional arrays with proper scaling of atom number to trap volume. By developing a tractable variational model, we were able to study droplet crystals and their excitations, and suggest potential creation of exotic ring and stripe states with experimentally feasible parameters. This work sets the stage for future research on two-dimensional dipolar supersolids in realistic settings.

Summary: The study investigates the phase diagram of two-dimensional quantum ferrofluids formed from ultracold atoms in different trap geometries, revealing the dominance of two-dimensional supersolid crystals at low densities and the presence of honeycomb, labyrinthine states, and a pumpkin phase at higher densities. The research sheds light on the various patterns of quantum ferrofluids and demonstrates that their occurrence is common in strongly dipolar interacting systems stabilized by effects beyond mean-field.
