Amplitude-exponent relation for the correlation length in the spherical model

Malte Henkel

For the critical spherical model in d=r+1 dimensions, finite-size calculations of the spin-spin and energy-energy correlation lengths suggest relations among the critical exponents and the finite-size scaling amplitudes of the correlation lengths similar to those obtained in (1+1) dimensions from conformal invariance. For antiperiodic boundary conditions, the results agree with numerical studies in the (2+1)-dimensional Ising model.

Casimir amplitudes in topological quantum phase transitions

M. A. R. Griffith, M. A. Contínentino

Topological phase transitions constitute a new class of quantum critical phenomena. They cannot be described within the usual framework of the Landau theory since, in general, the different phases cannot be distinguished by an order parameter, neither can they be related to different symmetries. In most cases, however, one can identify a diverging length at these topological transitions. This allows us to describe them using a scaling approach and to introduce a set of critical exponents that characterize their universality class. Here we consider some relevant models of quantum topological transitions associated with well-defined critical exponents that are related by a quantum hyperscaling relation. We extend to these models a finite-size scaling approach based on techniques for calculating the Casimir force in electromagnetism. This procedure allows us to obtain universal Casimir amplitudes at their quantum critical points. Our results verify the validity of finite-size scaling in these systems and confirm the values of the critical exponents obtained previously.

The relation between amplitudes and critical exponents in finite-size scaling

Philip D. Nightingale, Henk W. J. Blöte

The relation between critical exponents and the amplitude of the correlation length divergence at the critical point of two-dimensional systems as a function of finite size is investigated and generalised in two ways. Correlations more general than those of order-order type are included. A form appropriate for anisotropic systems is proposed. The authors present (a) exact results for the Ising and Gaussian models and (b) numerical results for the symmetric eight-vertex (Baxter), continuous q-state Potts, and continuous N-component cubic models.
