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 รฐAEp=2a; AEp=2aร and where electrons live in pockets centered at รฐp=a; 0ร or รฐ0; p=aร. The effective theory is used to investigate the m
