The low-energy physics of antiferromagnets is governed by their Goldstone bosons -the magnons -and it is described by a lowenergy effective field theory. In analogy to baryon chiral perturbation theory, we construct the effective field theory for magnons and holes in an antiferromagnet. It is a syst

We have constructed a systematic low-energy effective theory for hole-and electron-doped antiferromagnets, where holes reside in momentum space pockets centered at ðAEp=2a; AEp=2aÞ and where electrons live in pockets centered at ðp=a; 0Þ or ð0; p=aÞ. The effective theory is used to investigate the m
