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
