The spin-half Heisenberg antiferromagnet on the square-kagomé lattice: Ground state and low-lying excitations
J. Richter, J. Schulenburg, P. Tomczak +1
We discuss the ground state and the low-lying excitations of the spin-half Heisenberg antiferromagnet on the two-dimensional square-kagome lattice. This magnetic system belongs to…

The anisotropic quantum antiferromagnet on the Sierpinski gasket: Ground state and thermodynamics
Andreas Voigt, Wolfgang Wenzel, Johannes Richter +1
We investigate an antiferromagnetic s=1/2 quantum spin system with anisotropic spin exchange on a fractal lattice, the Sierpinski gasket. We introduce a novel approximative numeric…
