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…
Intertwined Superfluid and Density Wave Order in a -Orbital Bose Condensate
Simon Lieu, Andrew F. Ho, Derek K. K. Lee +1
We study a continuum model of the weakly interacting Bose gas in the presence of an external field with minima forming a triangular lattice. The second lowest band of the single-pa…
Optical signatures of antiferromagnetic ordering of fermionic atoms in an optical lattice
Francisco Cordobes Aguilar, Andrew F Ho, Janne Ruostekoski
We show how off-resonant light scattering can provide quantitative information on antiferromagnetic ordering of a two-species fermionic atomic gas in a tightly-confined two-dimensi…
Thermalisation of Local Observables in Small Hubbard Lattices
S. Genway, A. F. Ho, D. K. K. Lee
We present a study of thermalisation of a small isolated Hubbard lattice cluster prepared in a pure state with a well-defined energy. We examine how a two-site subsystem of the lat…
Ultracold Gases of Ytterbium: Ferromagnetism and Mott States in an SU(6) Fermi System
M. A. Cazalilla, A. F. Ho, M. Ueda
It is argued that ultracold quantum degenerate gas of ytterbium Yb atoms having nuclear spin exhibits an enlarged SU symmetry. Within the Landau Fermi liquid…
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…
