Critical Binder cumulant in two-dimensional anisotropic Ising models
W. Selke, L. N. Shchur
The Binder cumulant at the phase transition of Ising models on square lattices with various ferromagnetic nearest and next-nearest neighbour couplings is determined using mainly Mo…
Ground-state phases in antiferromagnetic spin-crossover chains
Carsten Timm, Ulrich Schollwöck
Spin-crossover molecules having a low-spin ground state and a low-lying excited high-spin state are promising components for molecular electronics. We theoretically examine one-dim…
Ising and anisotropic Heisenberg magnets with mobile defects
M. Holtschneider, R. Leidl, W. Selke
Motivated by experiments on (Sr,Ca,La)_14 Cu_24 O_41, a two-dimensional Ising model with mobile defects and a two-dimensional anisotropic Heisenberg antiferromagnet have been propo…
Ageing phenomena without detailed balance: the contact process
Tilman Enss, Malte Henkel, Alan Picone +1
The long-time dynamics of the 1D contact process suddenly brought out of an uncorrelated initial state is studied through a light-cone transfer-matrix renormalisation group approac…
