From one to two dimensions in quantum spin systems

A. Fledderjohann, K. -H. Mütter, M. -S. Yang +1

We study the first derivative of the staggered magnetization squared $d m^{†} (θ)^{2} / d θ$ and the second derivative $d^{2} e_{0} (θ) / d θ^{2}$ of the ground state energy per site. The parameter $θ…

Critical properties of 1-D spin 1/2 antiferromagnetic Heisenberg model

J. F. Audet, A. Fledderjohann, C. Gerhardt +4

We discuss numerical results for the 1-D spin 1/2 antiferromagnetic Heisenberg model with next-to-nearest neighbour coupling and in the presence of an uniform magnetic field. The m…
