Abstract Here we will consider the finite-size scaling, finite-size corrections and boundary effects for the critical two-dimensional free-fermion models. A short review of significant achievements and possibilities is given. However, this review is still far from completeness. We derive the exact finite-size corrections for the set of free models of statistical mechanics, including Ising model, dimer model, resistor network and spanning tree model under different boundary conditions. We have…

Finite-size correction to the scaling of free energy in the dimer model on a hexagonal domain
We consider dimer model on a hexagonal lattice. This model can be seen as a "pile of cubes in the box". The energy of configuration is given by the volume of the pile and the partition function is
Investigation of Finite-Size 2D Ising Model with a Noisy Matrix of Spin-Spin Interactions
TLDR
Analysis of changes in the thermodynamic properties of a spin system when it passes from the classical two-dimensional Ising model to the spin glass model, where spin-spin interactions are random in their values and signs shows that when the variance of the noise reaches one, there is a jump of the ground state from the fully correlated state to an uncorrelated state.
Specific heat and partition function zeros for the dimer model on the checkerboard B lattice: Finite-size effects.
TLDR
The partition function of the dimer model on a 2M×2N checkerboard B lattice wrapped on a torus is analyzed and very unusual behavior of the partition function zeros and the specific heat of the Dimer model is found.

TLDR
The exact asymptotic expansions of the logarithm of the partition function for each case of the spanning tree under free-boundary conditions are derived.
Conformal invariance, the central charge, and universal finite-size amplitudes at criticality.
We show that for conformally invariant two-dimensional systems, the amplitude of the finite-size corrections to the free energy of an infinitely long strip of width L at criticality is linearly
