A hole in the two-dimensional antiferromagnetic state moves coherently resonating with the quantum spin fluctuation and is accompanied by distortions in the local spin structure around it like a magnetic polaron which extends up to third near neighbour sites. Spin correlation functions suggest a twi
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
