A supersolid is a counter-intuitive state of matter that combines the frictionless flow of a superfluid with the crystal-like periodic density modulation of a solid1,2. Since the first prediction3 in the 1950s, experimental efforts to realize this state have focused mainly on helium, in which supersolidity remains unobserved4. Recently, supersolidity has also been studied in ultracold quantum gases, and some of its defining properties have been induced in spin–orbit-coupled Bose–Einstein… Expand
Supersolid symmetry breaking from compressional oscillations in a dipolar quantum gas
TLDR
This work demonstrates the breaking of two symmetries owing to the coexisting superfluid and crystal properties of a supersolid, and suggests the presence of two separate quantum phase transitions between the superfluid, supersolid and solid-like configurations. Expand
Two-dimensional supersolidity in a dipolar quantum gas.
TLDR
The extension of supersolid properties into two dimensions is demonstrated by preparing a supersolid quantum gas of dysprosium atoms on both sides of a structural phase transition similar to those occurring in ionic chains17-20, quantum wires21,22 and theoretically in chains of individual dipolar particles.

Exciting the Goldstone Modes of a Supersolid Spin-Orbit-Coupled Bose Gas.
TLDR
This work proposes accessible signatures of Goldstone modes in harmonically trapped spin-orbit-coupled Bose-Einstein condensates, where supersolidity appears in the form of stripes and provides evidence for the Goldstone mode associated with the translational motion of stripes. Expand
Supersolid phase of a spin-orbit-coupled Bose-Einstein condensate: a perturbation approach
The phase diagram of a Bose-Einstein condensate with Raman-induced spin-orbit coupling includes a stripe phase with supersolid features. In this work we develop a perturbation approach to study theExpand
Rotating a Supersolid Dipolar Gas.
TLDR
The moment of inertia of a harmonically trapped dipolar Bose-Einstein condensed gas is calculated as a function of the tunable scattering length parameter, providing the transition from the (fully) superfluid to the supersolid phase and eventually to an incoherent crystal of self-bound droplets.

Two-dimensional supersolidity in a circular trap
Dipolar condensates have recently been coaxed into supersolid phases supporting both superfluid and crystal excitations. While one-dimensional (1D) supersolids may be prepared via a rotonExpand
Exact relations for dipolar quantum gases
We establish that two-dimensional dipolar quantum gases admit a universal description, i.e., their thermodynamic properties are independent of details of the interaction at short distances. The onlyExpand
Berezinskii-Kosterlitz-Thouless transition in two-dimensional dipolar stripes
A two-dimensional quantum system of dipoles, with a polarization angle not perpendicular to the plane, shows a transition from a gas to a stripe phase. We have studied the thermal properties of theseExpand
Fate of the Amplitude Mode in a Trapped Dipolar Supersolid.
TLDR
This paper theoretically investigates the spectrum of elementary excitations of a trapped dipolar quantum gas across the BEC-supersolid phase transition and highlights how the symmetry-breaking nature of the supersolid state translates to finite-size systems. Expand

Excitation Spectrum of a Trapped Dipolar Supersolid and Its Experimental Evidence.

Theoretically, it is shown that, when entering the supersolid phase, two distinct excitation branches appear, respectively associated with dominantly crystal and superfluid excitations, and these results confirm infinite-system predictions, showing that finite-size effects play only a small qualitative role.
