Efimov Trimers near the Zero-crossing of a Feshbach Resonance

N. T. Zinner

Near a Feshbach resonance, the two-body scattering length can assume any value. When it approaches zero, the next-order term given by the effective range is known to diverge. We co…

Thermodynamics of Dipolar Chain Systems

J. R. Armstrong, N. T. Zinner, D. V. Fedorov +1

The thermodynamics of a quantum system of layers containing perpendicularly oriented dipolar molecules is studied within an oscillator approximation for both bosonic and fermionic…

Harmonically trapped dipolar fermions in a two-dimensional square lattice

Anne-Louise Gadsbolle, G. M. Bruun

We consider dipolar fermions in a two-dimensional square lattice and a harmonic trapping potential. The anisotropy of the dipolar interaction combined with the lattice leads to tra…

Field-induced long-lived supermolecules

S. -J. Huang, Y. -T. Hsu, H. Lee +4

We demonstrate that the long-lived bound states (super-molecules) can exist in the dilute limit when we tune the shape of effective potential between polar molecules by an external…

Metastability and Coherence of Repulsive Polarons in a Strongly Interacting Fermi Mixture

Christoph Kohstall, Matteo Zaccanti, Michael Jag +5

Ultracold Fermi gases with tuneable interactions represent a unique test bed to explore the many-body physics of strongly interacting quantum systems. In the past decade, experimen…

Universal Two-Body Spectra of Ultracold Harmonically Trapped Atoms in Two and Three Dimensions

N. T. Zinner

We consider the spectrum of two ultracold harmonically trapped atoms interacting via short-range interactions. The Green's function approach is used to unify the two and three dime…
