DESCRIPTION:It has been known for several years that it is pos
sible to construct exactly solvable lattice models
in 2+1 dimensions which realize a wide range of `
topological' phases\, which can be distinguished b
y their different `topological orders' characteriz
ing the exotic statistics of the excitations which
such phases exhibit. I will focus on a particula
r class of these models\, and describe a general p
rescription of how to tune the Hamiltonian through
a condensation transition\, resulting in a new to
pological phase with non-trivial topological order
. An intriguing feature of these transitions is t
hat\, for all of the models in the class I will di
scuss\, the dynamics of the phase transition is th
at of the transverse field Ising model. \n\n
