We will discuss Berry phase in family of quantum field theories and its implication to the low energy physics. The family is labelled by parameters which we promote to be spacetime-dependent background fields, and the Berry phase is equivalent to topological term of the parameters in the effective action. We use Berry phase to study diabolic points in the phase diagram and discuss applications including deconfined quantum criticality in 2+1d and new tests for boson/fermion dualities.
