Description
In recent experiments it has been seen that Bose-Einstein
condensation can be turned on and off by an external periodic potential.
As the potential strength is increased the system changes from a
Bose-Einstein condensate to a Mott-insulator. I will discuss these
concepts in a model of a hard core bose gas on a lattice, where the
phenomenon can be rigorously proved.
This will be a great talk!
