Elastic properties and thermodynamic anomalies of supersolids
Milan Rakic, Andrew F. Ho, Derek K. K. Lee
We study a supersolid in the context of a Gross-Pitaevskii theory with a non-local effective potential. We employ a homogenisation technique which allows us to calculate the elasti…

Feshbach resonant scattering of three fermions in one-dimensional wells
T. Duric, A. F. Ho, D . K. K. Lee
We study the weak-tunnelling limit for a system of cold 40K atoms trapped in a one-dimensional optical lattice close to an s-wave Feshbach resonance. We calculate the local spectru…
