Unified hydrodynamics for density and spin supersolids
Ashwath N. Madhusudan, Au-Chen Lee, P. B. Blakie +1
Two-component supersolids can exhibit in-phase or out-of-phase component density modulations, corresponding to density and spin supersolids, respectively. We formulate a general hy…
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…
Excitations and phase ordering of the spin-stripe phase of a binary dipolar condensate
Au-Chen Lee, D. Baillie, P. B. Blakie
We consider the ground states, excitations and dynamics of a quasi-two-dimensional binary dipolar Bose-Einstein condensate. Our focus is on the transition to a spin-stripe ground s…
Excitations of a binary dipolar supersolid
W. Kirkby, Au-Chen Lee, D. Baillie +4
We predict a rich excitation spectrum of a binary dipolar supersolid in a linear crystal geometry, where the ground state consists of two partially immiscible components with alter…
Stability of a flattened dipolar binary condensate: emergence of the spin roton
Au-Chen Lee, D. Baillie, P. B. Blakie
We develop theory for a two-component miscible dipolar condensate in a planar trap. Using numerical solutions and a variational theory we solve for the excitation spectrum and iden…
Miscibility and stability of dipolar bosonic mixtures
Au-Chen Lee, D. Baillie, P. B. Blakie +1
Combining two Bose-Einstein condensates (BECs) may result in a miscible or immiscible mixture, or even a violent implosion. We theoretically demonstrate that dipolar two-component…
Numerical calculation of dipolar quantum droplet stationary states
Au-Chen Lee, D. Baillie, P. B. Blakie
We describe and benchmark a method to accurately calculate the quantum droplet states that can be produced from a dipolar Bose-Einstein condensate. Our approach also allows us to c…
Excitations of a vortex line in an elongated dipolar condensate
Au-Chen Lee, D. Baillie, R. N. Bisset +1
We characterise the properties of a vortex line in an elongated dipolar Bose-Einstein condensate. Increasing the strength of the dipole-dipole interactions (DDIs) relative to the s…
