Description
We provide a systematic derivation of effective actions describing the low-energy sector of frustrated quantum Heisenberg models. The method presented is very general and can be applied to any antiferromagnetic Heisenberg model, irrespective of the number of additional frustrating interactions or of the type of lattice. We show that the effective action is completely governed by the topology of the ground state. Qualitative aspects of the T=0 phase diagram are discussed
