Topological quantum phase transitions of ultracold fermions in optical lattices
R. W. Cherng, C. A. R. Sá de Melo
We consider the possibility of topological quantum phase transitions of ultracold fermions in optical lattices, which can be studied as a function of interaction strength or atomic…

Roton softening and supersolidity in Rb spinor condensates
R. W. Cherng, E. Demler
Superfluids with a tendency towards periodic crystalline order have both a phonon and roton like spectrum of collective modes. The softening of the roton spectrum provides one rout…
