Acoustic fluctuations of two-dimensional dipolar supersolids
P. Blair Blakie
We investigate the microscopic structure of the long-wavelength acoustic excitations of two-dimensional dipolar supersolids with triangular and honeycomb crystal order. Using Bogol…
Excitations and anisotropic sound in planar dipolar supersolids with tilted dipoles
Reuben Cook, Au-Chen Lee, P. Blair Blakie
We investigate the collective excitations of anisotropic dipolar supersolids in planar confinement, focusing on triangular and stripe phases in situations where the dipoles are tit…
Stochastic Gross-Pitaevskii theory for a spin-1 Bose gas: Application to superfluidity in two dimensions
Andrew P. C. Underwood, P. B. Blakie
This paper develops and implements the stochastic projected Gross-Pitaevskii equation for spin-1 Bose gases, addressing key considerations for numerical simulations. As an applicat…
Honeycomb supersolid -- Dirac points and shear-instability induced crystal transitions
P. B. Blakie
The honeycomb supersolid state is predicted to form in a dipolar Bose-Einstein condensate with a planar confining potential. Our results for its excitation spectrum reveal the gapl…
Supersolid spectroscopy
L. M. Platt, D. Baillie, P. B. Blakie
We develop a linear response theory to provide a unified description of two recent spectroscopy protocols for probing one-dimensional supersolid states realized in cold-atom system…
Excitations of a two-dimensional supersolid
Elena Poli, Danny Baillie, Francesca Ferlaino +1
We present a theoretical study of the excitations of the two-dimensional supersolid state of a Bose-Einstein condensate with either dipole-dipole interactions or soft-core interact…
