Born-Oppenheimer description of two atoms in a combined oscillator and lattice trap
Ole Søe Sørensen, Klaus Mølmer
We analyze the quantum states of two atoms in a combined harmonic oscillator and periodic lattice trap in one spatial dimension. In the case of tight-binding and only nearest neigh…
Relative and center-of-mass motion in the attractive Bose-Hubbard model
Ole Søe Sørensen, Søren Gammelmark, Klaus Mølmer
We present first-principle numerical calculations for few particle solutions of the attractive Bose-Hubbard model with periodic boundary conditions. We show that the low-energy man…
Adiabatic cooling of a tunable Bose-Fermi mixture 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.…
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.…
Semi-analytic Faddeev solution to the -boson problem with zero-range interactions
T. Sogo, O. Sørensen, A. S. Jensen +1
We study two-body correlations for identical bosons by use of the hyperspherical adiabatic expansion method. We use the zero-range interaction and derive a transcendental equat…
Two-component boson systems with hyperspherical coordinates
T Sogo, O Sørensen, A S Jensen +1
The effective potential is computed for two boson systems in one trap as a function of their two individual hyperadii and the distance between their centers. Zero-range interaction…
