Spiral phases and two-particle bound states from a systematic low-energy effective theory for magnons, electrons, and holes in an antiferromagnet

C. Brügger, C. P. Hofmann, F. Kämpfer +3

We have constructed a systematic low-energy effective theory for hole- and electron-doped antiferromagnets, where holes reside in momentum space pockets centered at $(\pm\fracπ{2a}…

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 $(\pm \frac{π}{2 a}, \pm \frac{π}{2 a})$ , in lightly electron-doped antiferromagnets the charged quasiparticles resid…
