Influence of the spin quantum number on the zero-temperature phase transition in the square lattice - model
R. Darradi, J. Richter, D. J. J. Farnell
We investigate the phase diagram of the Heisenberg antiferromagnet on the square lattice with two different nearest-neighbor bonds and (- model) at zero temperature…

Influence of Ising-anisotropy on the zero-temperature phase transition in the square lattice spin-1/2 J-J' model
R. Darradi, J. Richter, S. E. Krueger
We use a variational mean-field like approach, the coupled cluster method (CCM) and exact diagonalization to investigate the ground-state order-disorder transition for the square l…
