Finite lattice calculation of the quantum mechanical n-vector model
M. Kolb, Rémi Jullien, Pierre M. Pfeuty
The truncated quantum mechanical n-vector model in one dimension is studied by means of the phenomenological renormalisation group (PRG) and the block renormalisation group (BRG) for general values of n. Particular emphasis is put on the extrapolation of the finite size results using the finite size scaling hypothesis. Accurate estimates of the critical properties can be made for 0<or approximately=n<or approximately=2. The two methods used are critically compared.
