A Monte Carlo examination for the numerical values of universal quantities in spatial dimension two
Fu-Jiun Jiang
By simulating a two-dimensional (2D) dimerized spin-1/2 antiferromagnet with the quantum Monte Carlo method, the numerical values of two universal quantities associated with the qu…
Symmetry Analysis of Holes Localized on a Skyrmion in a Doped Antiferromagnet
N. D. Vlasii, C. P. Hofmann, F. -J. Jiang +1
We use the low-energy effective field theory for holes coupled to the staggered magnetization in order to investigate the localization of holes on a Skyrmion in a square lattice an…
Systematic Low-Energy Effective Field Theory for Magnons and Holes in an Antiferromagnet on the Honeycomb Lattice
F. Kämpfer, B. Bessire, M. Wirz +3
Based on a symmetry analysis of the microscopic Hubbard and t-J models, a systematic low-energy effective field theory is constructed for hole-doped antiferromagnets on the honeyco…
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…
Systematic Effective Field Theory Investigation of Spiral Phases in Hole-Doped Antiferromagnets on the Honeycomb Lattice
F. -J. Jiang, F. Kämpfer, C. P. Hofmann +1
Motivated by possible applications to the antiferromagnetic precursor of the high-temperature superconductor NaCoOyHO, we use a systematic low-energy effective fie…
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…
