Properties of the two-dimensional spin-1/2 Heisenberg model on a honeycomb lattice with interlayer coupling
The magnetic properties of the two-dimensional S = 1/2 (quantum) antiferromagnetic Heisenberg model on a honeycomb lattice with and without interlayer coupling are studied by means of a continuous Euclidean time Quantum-Monte-Carlo algorithm. The internal energy, the magnetic susceptibility and th...

| description |
The magnetic properties of the two-dimensional S = 1/2 (quantum) antiferromagnetic Heisenberg model on
a honeycomb lattice with and without interlayer coupling are studied by means of a continuous Euclidean
time Quantum-Monte-Carlo algorithm. The internal energy, the magnetic susceptibility and the staggered
magnetization are determined in the full temperature range. For the two-dimensional system the groundstate
energy/bond is found to be Ehc 0 = -0:36303(13), and the zero temperature staggered magnetization
mst = 0:2681(8). For coupled planes of honeycomb systems a phase transition from an ordered phase to a
disordered phase is found at T/J = 0:695(10). |
