Abstract

An Ising model with three-spin interaction is investigated by finite-size scaling applying free boundary conditions. The surface critical properties of the model were determined by conformal invariance. Taking into account logarithmic corrections the surface critical exponents obtained are in accordance with the four-state Potts values.

Critical behaviour and logarithmic corrections of a quantum model with three-spin interaction

Carlo Vanderzande, Ferenc Iglói

Extended finite-size scaling and series expansion methods are used to determine the critical properties of the one-dimensional quantum Ising model with three-spin interaction. By supposing the presence of logarithmic corrections the universality class of the model is investigated. The results obtained by different methods support the conjecture that the model belongs to the same universality class as the four-state Potts model.

Conformal invariance and critical behavior of a quantum Hamiltonian with three-spin coupling in a longitudinal field

K. A. Penson, Jean‐Marc Debierre, Loïc Turban

The critical behavior of a quantum spin chain with three-spin coupling in transverse and longitudinal fields is studied by finite-size scaling. The phase diagram and the thermal and magnetic critical exponents are obtained. Conformal invariance is used to extract the value of the central charge or conformal anomaly c. The results strongly suggest that for a finite longitudinal field the model belongs to the same universality class as the two-dimensional three-state Potts model.

Conformal invariance and the critical behaviour of a quantum spin Hamiltonian with three-spin coupling

Francisco Castilho Alcaraz, Michael N. Barber

A quantum spin model with three-spin coupling is studied by finite-lattice methods. The critical indices nu and alpha are obtained by standard finite-size scaling analysis. Conformal invariance is used to estimate the exponents nu and eta , the central charge or conformal anomaly c and the anomalous dimension of a spin 1/4 parafermion. The authors conclude that the model belongs to the same universality class as the four-state Potts and Baxter-Wu models, although the convergence of the various finite lattice estimators is extremely slow.

On the scaling behaviour and conformal properties of triangular Ising model with three-spin interactions at the critical point

M. Ghasemi Nezhadhaghighi

Abstract The scaling behaviour and conformal properties of a triangular Ising model with three-spin interactions at the critical point are studied using extensive Monte Carlo simulations. We show that in the continuum limit the external perimeter of spin clusters are conformally invariant and statistically equivalent to Schramm–Loewner evolution (SLE κ ) curves with diffusivity κ = 4, indicating that the loop ensembles associated with the critical Ising model with three-spin interactions, belonging to the universality class of domain walls in the four-states Potts model. The left-passage probabilities, distribution of the winding angle, and the driving function distribution for the interfaces are consistent with each other. We also study many geometrical properties of the critical interfaces to characterize the fractal structure and the other scaling properties of conformal loop ensembles. To this end, the fractal dimension of contours, the scaling properties of length and areas distributions and Zipf’s laws, are demonstrated numerically. Our results are compatible with the hyper-scaling relation for spin models.

Conformal invariance, finite-size scaling and surface magnetic exponent of the Potts model in two dimensions

Carlo Vanderzande, Attilio L. Stella

The analysis of renormalisation group equations for the q-state Potts model in two dimensions is generalised to include the presence of a surface field H s besides the bulk one, H B . Combined with conformal invariance results, this allows prediction of a surface susceptibility behaviour delta 2/f delta H s delta H B approximately L -1/8 (1-C'lnL) 15/16 for a q=4 system of size L at the critical temperature. This prediction is checked by a Monte Carlo based finite-size scaling analysis, which also nicely reproduces the exact and conjectured magnetic surface exponents for q=2 and 3, respectively. For the Baxter-Wu model similar methods give results consistent with the q=4 behaviour without logarithmic corrections (c'=0).

Critical-off-critical interface in the Ising quantum chain and conformal invariance

Bertrand Berche, Loïc Turban

The low-energy excitation spectrum of an Ising quantum chain in a transverse field which is critical (h=J=1) for 1<or=n<or=L/2 and off-critical (h not=J) for L/2(n<or=L is calculated up to O(L -1 ). Interface critical exponents are determined numerically in the odd sector and exactly in the even sector using finite-size scaling. One gets an ordinary surface transition when h)J and an extraordinary surface transition when h(J. The gap-exponent relation is verified, the mass gaps and the level degeneracy are in agreement with conformal invariance.
