Spin dynamics across the superfluid-insulator transition of spinful bosons
Stephen Powell, Subir Sachdev
Bosons with non-zero spin exhibit a rich variety of superfluid and insulating phases. Most phases support coherent spin oscillations, which have been the focus of numerous recent e…

Excited state spectra at the superfluid-insulator transition out of paired condensates
Stephen Powell, Subir Sachdev
We describe gapped single-particle and collective excitations across a superfluid to insulator quantum phase transition of particles (bosons or fermions) in a periodic potential, w…

Depletion of the Bose-Einstein condensate in Bose-Fermi mixtures
Stephen Powell, Subir Sachdev, Hans Peter Buchler
We describe the properties of a mixture of fermionic and bosonic atoms, as they are tuned across a Feshbach resonance associated with a fermionic molecular state. Provided the numb…
