Accuracy of quantum simulators with ultracold dipolar molecules: A quantitative comparison between continuum and lattice descriptions
Michael Hughes, Axel U. J. Lode, Dieter Jaksch, Paolo Molignini
Abstract
The authors perform a quantitative comparison between the continuum description of a one-dimensional gas of dipolar bosons in an optical lattice and the single-band Bose-Hubbard lattice model that it simulates. Discrepancies are found in regimes with strong dipole-dipole interactions and high densities in the continuum system.
