l Abstract. We use the density-matrix renormalization-group (DMRG) algorithm and finite-
l
a size scaling to study a supersymmetric (SUSY) spin chain that models plateau transitions
h in the integer quantum Hall effect. To illustrate the method, we first present results for the
- S = 1 antiferromagnetic spin chain. Different scaling behavior of the dimerization operator is
s
e obtained for the Haldane phase, the dimerized phase, and at the critical point separating the
two phases. We then investigate the supersymmetric spin chain. As the on-site Hilbert space
m has infinite dimension, it is non-compact. We present DMRG calculations for supersymmetric
.
t truncations of the on-site Hilbert space and also for non-supersymmetric truncations. These
a two cases scale differently, in accord with a Lieb-Schultz-Mattis type theorem.
