Systematic Low-Energy Effective Field Theory for Electron-Doped Antiferromagnets
C. Brügger, C. P. Hofmann, F. Kämpfer +3
In contrast to hole-doped systems which have hole pockets centered at , in lightly electron-doped antiferromagnets the charged quasiparticles resid…

Homogeneous versus Spiral Phases of Hole-doped Antiferromagnets: A Systematic Effective Field Theory Investigation
C. Brügger, C. P. Hofmann, F. Kämpfer +2
Using the low-energy effective field theory for magnons and holes -- the condensed matter analog of baryon chiral perturbation theory for pions and nucleons in QCD -- we study diff…

From the Hubbard Model to a Systematic Low-Energy Effective Field Theory for Magnons and Holes in an Antiferromagnet
C. Brügger, F. Kämpfer, M. Moser +2
The low-energy physics of antiferromagnets is governed by their Goldstone bosons -- the magnons -- and it is described by a low-energy effective field theory. In analogy to baryon…
