Critical Behaviour of the 3d Gross-Neveu and Higgs-Yukawa Models
L. Karkkainen, R. Lacaze, P. Lacock +1
We measure the critical exponents of the three dimensional Gross-Neveu model with two four-component fermions. The exponents are inferred from the scaling behaviour of observables…

Dynamical Properties of a Haldane Gap Antiferromagnet
O. Golinelli, Th. Jolicoeur, R. Lacaze
We study the dynamic spin correlation function of a spin one antiferromagnetic chain with easy-plane single-ion anisotropy. We use exact diagonalization by the Lancz\H os method fo…
