Monte Carlo Determination of the Low-Energy Constants of a Spin 1/2 Heisenberg Model with Spatial Anisotropy
F. J. Jiang, F. Kämpfer, M. Nyfeler
Motivated by the possible mechanism for the pinning of the electronic liquid crystal direction in YBCO as proposed in \cite{Pardini08}, we use the first principles Monte Carlo meth…
Nested Cluster Algorithm for Frustrated Quantum Antiferromagnets
M. Nyfeler, F. -J. Jiang, F. Kämpfer +1
Simulations of frustrated quantum antiferromagnets suffer from a severe sign problem. We solve the ergodicity problem of the loop-cluster algorithm in a natural way and apply a pow…
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…
