The Molecular Hubbard Hamiltonian: Field Regimes and Molecular Species
M. L. Wall, Erman Bekaroglu, Lincoln D. Carr
The molecular Hubbard Hamiltonian (MHH) naturally arises for ultracold ground state polar alkali dimer molecules in optical lattices. We show that, unlike ultracold atoms, differen…
The nonlinear Dirac equation: Preparation and stability of relativistic vortices in Bose-Einstein condensates
L. H. Haddad, K. M. O'Hara, Lincoln D. Carr
We propose a detailed experimental procedure for preparing relativistic vortices, governed by the nonlinear Dirac equation, in a two-dimensional Bose-Einstein condensate (BEC) in a…
Vortex macroscopic superpositions in ultracold bosons in a double-well potential
M. A. Garcia-March, Lincoln D. Carr
We study macroscopic superpositions in the orbital rather than the spatial degrees of freedom, in a three-dimensional double-well system. We show that the ensuing dynamics of i…
