Hubbard model for atomic impurities bound by the vortex lattice of a rotating BEC
T. H. Johnson, Y. Yuan, W. Bao +3
We investigate cold bosonic impurity atoms trapped in a vortex lattice formed by condensed bosons of another species. We describe the dynamics of the impurities by a bosonic Hubbar…
Capturing long range correlations in two-dimensional quantum lattice systems using correlator product states
S. Al-Assam, S. R. Clark, C. J. Foot +1
We study the suitability of correlator product states for describing ground-state properties of two-dimensional spin models. Our ansatz for the many-body wave function takes the fo…
The Moment of Inertia and the Scissors Mode of a Bose-condensed Gas
O. M. Marago', G. Hechenblaikner, E. Hodby +2
We relate the frequency of the scissors mode to the moment of inertia of a trapped Bose gas at finite temperature in a semi-classical approximation. We apply these theoretical resu…
Temperature Dependence of Damping and Frequency Shifts of the Scissors Mode of a trapped Bose-Einstein Condensate
Onofrio Marago', Gerald Hechenblaikner, Eleanor Hodby +1
We have studied the properties of the scissors mode of a trapped Bose-Einstein condensate of Rb atoms at finite temperature. We measured a significant shift in the frequency…
