Exact phase diagrams for an Ising model on a two-layer Bethe lattice

TL;DR: Using an iteration technique, exact expressions for the free energy and the magnetization of an Ising model on a two-layer Bethe lattice with intralayer coupling constants J1 and J2 for the first and the second layer, respectively, and interlayer coupling constant J3 between the two layers are obtained.
Journal ArticleDOI

Exact universal amplitude ratios for two-dimensional Ising models and a quantum spin chain.

TL;DR: In this article, the amplitude ratio b(k)/a(k) is shown to be (2(2k)-1)/(2 (2k-1)-1) for square, honeycomb, and plane-triangular lattices.
Journal ArticleDOI

Finite-size behavior of the critical Ising model on a rectangle with free boundaries.

TL;DR: It is found that not only the corner free energy but also the corner internal energy and specific heat are geometry independent, i.e., independent of aspect ratio, and the implication of this finding for finite-size scaling is discussed.
Journal ArticleDOI

Geometry, thermodynamics, and finite-size corrections in the critical Potts model.

TL;DR: It is found that the number of clusters of the QBCPM has an energy-like singularity for q not equal to 1, which is reached and supported by exact results, numerical simulation, and scaling arguments.
Journal ArticleDOI

Shape-dependent finite-size effect of the critical two-dimensional Ising model on a triangular lattice.

TL;DR: The conformal field theory prediction that the corner free energy is universal is confirmed and logarithmic corrections in higher-order terms are found in the critical free energy for the rhomboid, trapezoid, and hexagonal systems, which are absent for the triangular and rectangular systems.
