Tensor Renormalization-Group study of the surface critical behavior of a frustrated two-layer Ising model
Christophe Chatelain
Two replicas of a 2D Ising model are coupled by frustrated spin-spin interactions. It is known that this inter-layer coupling is marginal and that the bulk critical behavior belong…

First-order transition and marginal critical behavior in a novel 2D frustrated Ising model
Christophe Chatelain
The phase diagram of a novel two-dimensional frustrated Ising model with both anti-ferromagnetic and ferromagnetic couplings is studied using Tensor-Network Renormalization-Group t…

CTMRG study of the critical behavior of an interacting-dimer model
Christophe Chatelain
The critical behavior of a dimer model with an interaction favoring parallel dimers in each plaquette of the square lattice is studied numerically by means of the Corner Transfer M…
