Dimensional Crossover in the Superfluid-Supersolid Quantum Phase Transition

Giulio Biagioni et al.

Summary: Supersolids are a quantum phase of matter where the global phase and translational symmetries are spontaneously broken. By experiment and theory, it has been found that the phase transition of supersolids can be discontinuous or continuous, and the dimensional crossover is controlled by confinement and atom number.

Supersolid-like square- and honeycomb-lattice crystallization of droplets in a dipolar condensate

Luis E. Young-S et al.

Summary: We observe the crystallization of droplets in square and honeycomb lattice structures in a quasi-two-dimensional trapped dipolar condensate. These three types of crystallization can occur under the same atomic interaction and trap frequencies. The energy of all three crystallizations follows a scaling relation with the number of atoms, indicating their energetic plausibility. The square lattice crystallization with an occupied central site is a potential candidate for future experimental observation.

Moment of inertia and dynamical rotational response of a supersolid dipolar gas

S. M. Roccuzzo et al.

Summary: We show that by studying the time-dependent response of a trapped gas subjected to a sudden rotation, we can determine the moment of inertia of dipolar supersolid configurations. One-dimensional arrays of droplets provide accurate access to the moment of inertia through the frequency of scissors oscillation, while two-dimensional-like configurations exhibit low-frequency resonances indicating the presence of significant rigid body components in the rotational motion.

Supersolid edge and bulk phases of a dipolar quantum gas in a box

S. M. Roccuzzo et al.

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.

Interspecies interactions in an ultracold dipolar mixture

C. Politi et al.

Summary: In this study, the influence and control of dipole-dipole interactions (DDIs) on the total interspecies interaction in an erbium-dysprosium mixture were experimentally and theoretically investigated. By rotating the dipole orientation, the effect of the long-range and anisotropic DDI on the in-trap displacements of the erbium and dysprosium clouds was tuned. A theoretical description based on an extended Gross-Pitaevskii theory was presented for the binary system, including beyond mean-field terms for the single-species. Lower and upper bounds for the interspecies scattering length were predicted. This research is significant for exploring the experimentally unexplored dipolar miscibility-immiscibility phase diagram and realizing quantum droplets and supersolid states with heteronuclear dipolar mixtures.

Phase coherence in out-of-equilibrium supersolid states of ultracold dipolar atoms

P. Ilzhoefer et al.

Summary: The study investigates the response of dipolar supersolids to interaction quenches, finding a parameter regime where the out-of-equilibrium state rephases before gradually relaxing into an incoherent droplet array. Collective mode excitations caused by the interaction quench connect to phonons in solids and affect the phase dynamics.

Quantum Droplets of Dipolar Mixtures

R. N. Bisset et al.

Summary: The recent achievement of two-component dipolar Bose-Einstein condensates has opened up exciting possibilities for studying mixtures of ultradilute quantum liquids, resulting in various ground-state phases. The formation of self-bound immiscible droplets is possible due to mutual nonlocal intercomponent attraction. Additionally, quantum fluctuations in the majority component critically modify the miscibility of impurities.

Quantum Droplet States of a Binary Magnetic Gas

Joseph C. Smith et al.

Summary: Quantum droplets can emerge in bosonic binary magnetic gases through the interplay of short- and long-ranged interactions, as well as quantum fluctuations. An extended mean field theory was developed to predict the equilibrium and dynamical properties of these droplets, revealing miscible and immiscible droplet states. The study also found that a single-component self-bound droplet can bind another magnetic component due to interspecies dipole-dipole interactions, with implications for experiments using mixtures of highly magnetic lanthanide atoms.

Density Fluctuations across the Superfluid-Supersolid Phase Transition in a Dipolar Quantum Gas

J. Hertkorn et al.

Summary: Experimental measurement of density fluctuations across the superfluid-supersolid phase transition provides insight into the static structure factor, spectrum of elementary excitations, and dominant fluctuation patterns. Strong response in static structure factor and presence of a distinct roton minimum in the dispersion relation suggest the presence of roton modes at the quantum critical point in the supersolid state. The study also indicates that the supersolid state supports both superfluid and crystal phonons.

Oscillations of a quasi-one-dimensional dipolar supersolid

B. Kh Turmanov et al.

Summary: This study investigates the properties of a supersolid state in quasi-one-dimensional dipolar Bose-Einstein condensate, considering two possible mechanisms of realization within the framework of the Lee-Huang-Yang theory. Both mechanisms are emphasized in the formation of supersolid properties. Numerical simulations of the extended Gross-Pitaevskii equation are used to identify distinct oscillation frequencies associated with the superfluid fraction and crystalline components of the supersolid.

Maintaining supersolidity in one and two dimensions

E. Poli et al.

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.

Vortex properties in the extended supersolid phase of dipolar Bose-Einstein condensates

Francesco Ancilotto et al.

Summary: The properties of singly quantized linear vortices in the supersolid phase of a dipolar Bose-Einstein condensate are studied, revealing that vortices in the supersolid phase are localized and cannot move freely, with energy barriers calculated for their motion. The dynamics of a vortex dipole in the supersolid phase differs significantly from that in the superfluid phase, as the vortices approach each other through a series of jumps until annihilation.

Persistent currents in toroidal dipolar supersolids

M. Nilsson Tengstrand et al.

Summary: This study investigates the rotational properties of a dipolar Bose-Einstein condensate trapped in a toroidal geometry and discovers distinct behaviors of the condensate in superfluid and supersolid phases. The toroidal dipolar condensate can support a supersolid persistent current, and superfluid condensates may enter the supersolid phase when angular momentum is introduced. The rotating toroidal supersolid exhibits hysteretic behavior depending on the superfluid fraction of the condensate.
