Description |
Experimental advances over the last decade or so have made it possible to create optical lattices of cold atoms. The study of interacting bosonic and fermionic atoms in such lattices is currently a very active area of research. In this talk, I will describe various interesting phases that can be obtained in systems of interacting bosons in one dimensional lattices. I will show that in the presence of frustration and further neighbour hopping or interactions, it is possible to obtain phases other than the usual superfluid and featureless Mott phases. In particular, I will show that it is possible for Mott phases with broken symmetry, Haldane-type phases and "chiral" superfluid phases to exist in these systems. Time permitting, I will also describe phases and phase transitions of bosons with spin on optical lattices. |
