Critical Behaviour of One-particle Spectral Weights in the Transverse Ising Model
C. J. Hamer, J. Oitmaa, Weihong Zheng +1
We investigate the critical behaviour of the spectral weight of a single quasiparticle, one of the key observables in experiment, for the particular case of the transverse Ising mo…

The J1-J2 model: First order phase transition versus deconfinement of spinons
J. Sirker, Zheng Weihong, O. P. Sushkov +1
We revisit the phase transition from the Néel ordered to a valence bond solid (VBS) state in the two-dimensional antiferromagnetic Heisenberg model. In the first part we…
