Two-Hole Bound States from a Systematic Low-Energy Effective Field Theory for Magnons and Holes in an Antiferromagnet
C. Brügger, F. Kämpfer, M. Moser +2
Identifying the correct low-energy effective theory for magnons and holes in an antiferromagnet has remained an open problem for a long time. In analogy to the effective theory for…

Magnon-mediated Binding between Holes in an Antiferromagnet
C. Bruegger, F. Kaempfer, M. Pepe +1
The long-range forces between holes in an antiferromagnet are due to magnon exchange. The one-magnon exchange potential between two holes is proportional to cos(2ϕ)/r^2 where r is…
