โœฆ Synopsis

By the finite-size scaling technique, the dynamical critical exponent of the one-dimensional random transverse-Ising model is evaluated. The finite-size scaling of the average and the distribution of the energy gap in each sample are also discussed. The exponent seems to vary depending on the parameters in the probability distribution function of our model.

The one-dimensional Ising model with a transverse field is solved exactly by transforming the set of Pauli operators to a new set of Fermi operators. The elementary excitations, the ground-state energy and the free energy are found. The instantaneous correlation function between any two spins is cal
