We explore the ground states and quantum phase transitions of two-dimensional, spin S = 1/2, antiferromagnets by generalizing lattice models and duality transforms introduced by Sachdev and , Mod. Phys. Lett. B 4, 1043). The minimal model for square lattice antiferromagnets is a lattice discretizati
Transition stati theory is tested against accurate rate constants for the colLLaear H + Ef P reaction oa a realistic potential energy surface. For this reaction the theory is fafrfy accurate at higti'temperatures but is very inaccurate at low temperatures.
