Tricritical Ising Model near criticality
The most relevant thermal perturbation of the continuous d = 2 minimal conformal theory with c = 7/10 (Tricritical Ising Model) is treated here. This model describes the scaling region of the φ universality class near the tricritical point. The problematic IR divergences of the naive perturbative expansion around conformal theories are dealt within the OPE approach developed at all orders by th...
متن کاملDeep Learning the Ising Model Near Criticality
It is well established that neural networks with deep architectures perform better than shallow networks for many tasks in machine learning. In statistical physics, while there has been recent interest in representing physical data with generative modelling, the focus has been on shallow neural networks. A natural question to ask is whether deep neural networks hold any advantage over shallow n...
متن کاملThe Surface Tension near Criticality of the 2d-ising Model
For the two dimensional Ising model, we construct the adequate surface tension near criticality. The latter quantity has been shown [9] to play a central role in the study of phase coexistence in a joint limit where the temperature approaches the critical point from below and simultaneously the size of the system increases fast enough.
متن کاملTricritical Ising Model with a Boundary ∗
We study the integrable and supersymmetric massivê φ (1,3) deformation of the tricritical Ising model in the presence of a boundary. We use constraints from su-persymmetry in order to compute the exact boundary S-matrices, which turn out to depend explicitly on the topological charge of the supersymmetry algebra. We also solve the general boundary Yang-Baxter equation and show that in appropria...
متن کاملUniversal ratios in the 2D tricritical ising model
We consider the universality class of the two-dimensional tricritical Ising model. The scaling form of the free energy leads to the definition of universal ratios of critical amplitudes which may have experimental relevance. We compute these universal ratios by a combined use of results coming from perturbed conformal field theory, integrable quantum field theory, and numerical methods.
