Tilted dipolar bosons in the quasi-two-dimensional regime: from liquid stripes to droplets
We characterize a system of tilted dipoles in a quasi-two-dimensional (flattened) geometry and in the thermodynamic limit. We consider a finite trapping in the ¿ axis achievable in current experiments. We compute the phase diagram of the system at its equilibrium density for high tilting angles, whe...

| Sumario: | We characterize a system of tilted dipoles in a quasi-two-dimensional (flattened) geometry and in the thermodynamic limit. We consider a finite trapping in the ¿ axis achievable in current experiments. We compute the phase diagram of the system at its equilibrium density for high tilting angles, where it becomes self-bound, and a striped liquid state emerges. To characterize the system, we perform a variational calculation, which is benchmarked with the solution of the extended Gross-Pitaevskii equation. We connect the phenomenology in the thermodynamic limit to the physics of the finite-size system, provide parameters for the realization of potentially supersolid striped states, and study the critical number for dipolar droplet formation. Our results are helpful to guide potential experiments in the study of dipolar atoms in quasi-two-dimensional geometries in the dipole-dominated regime. |
