P-band induced self-organization and dynamics with repulsively driven ultracold atoms in an optical cavity

P. Zupancic, D. Dreon, X. Li +6

We investigate a Bose-Einstein condensate strongly coupled to an optical cavity via a repulsive optical lattice. We detect a stable self-ordered phase in this regime, and show that…

Superradiance induced particle flow via dynamical gauge coupling

Wei Zheng, Nigel R. Cooper

We study fermions that are gauge-coupled to a cavity mode via Raman-assisted hopping in a one dimensional lattice. For an infinite lattice, we find a superradiant phase with infini…

Pressure Dependent Wall Relaxation in Polarized He Gaseous Cells

C. Peng, W. Zheng, P. -H. Chu +2

Pressure dependence of longitudinal relaxation time (T) due to the cell wall was observed previously at both room temperature and low temperature in valved Rb-coated refillable…

Ground state and finite temperature signatures of quantum phase transitions in the half-filled Hubbard model on a honeycomb lattice

Thereza Paiva, R. T. Scalettar, W. Zheng +2

We investigate ground state and finite temperature properties of the half-filled Hubbard model on a honeycomb lattice using quantum monte carlo and series expansion techniques. Unl…

Order and disorder in the triangular-lattice t-J-V model at 2/3 electron density

W. Zheng, J. Oitmaa, C. J. Hamer +1

Motivated by the recent discovery of superconductivity in NaCoOHO, we use series expansion methods and cluster mean-field theory to study spontaneous charge orde…

Ferrimagnetism and compensation points in a decorated 3D Ising models

J. Oitmaa, W. Zheng

We give a precise numerical solution for decorated Ising models on the simple cubic lattice which show ferromagnetism, compensation points, and reentrant behaviour. The models, con…
