Scattering of matter wave solitons on localized potentials
Sidse Damgaard Hansen, Nicolai Nygaard, Klaus Mølmer
We present numerical and analytical results for the reflection and transmission properties of matter wave solitons impinging on localized scattering potentials in one spatial dimen…
Honeycomb optical lattices with harmonic confinement
J. Kusk Block, N. Nygaard
We consider the fate of the Dirac points in the spectrum of a honeycomb optical lattice in the presence of a harmonic confining potential. By numerically solving the tight binding…
Statistical mechanics of a Feshbach coupled Bose-Fermi gas in an optical lattice
O. Soe Sorensen, N. Nygaard, P. B. Blakie
We consider an atomic Fermi gas confined in a uniform optical lattice potential, where the atoms can pair into molecules via a magnetic field controlled narrow Feshbach resonance.…
Two-channel Feshbach physics in a structured continuum
N. Nygaard, R. Piil, K. Molmer
We analyze the scattering and bound state physics of a pair of atoms in a one-dimensional optical lattice interacting via a narrow Feshbach resonance. The lattice provides a struct…
Adiabatic Phase Diagram of an Ultracold Atomic Fermi Gas with a Feshbach Resonance
S. Watabe, T. Nikuni, N. Nygaard +2
We determine the adiabatic phase diagram of a resonantly-coupled system of Fermi atoms and Bose molecules confined in the harmonic trap by using the local density approximation. Th…
Adiabatic Phase Diagram on Degenerate Fermi Gas with Feshbach-Resonance
S. Watabe, T. Nikuni, N. Nygaard +2
We determine the adiabatic phase diagrams for a resonantly-coupled system of Fermi atoms and Bose molecules confined in a harmonic trap by using the local density approximation. Th…
