Baxter–Wu model with fixed magnetization

Martinos, S.S.; Malakis, A.; Hadjiagapiou, I. - In: Physica A: Statistical Mechanics and its Applications 366 (2006) C, pp. 273-280

We study Baxter–Wu triangular model with fixed magnetization in the framework of canonical and microcanonical ensemble, constructing the density of states by Wang–Landau algorithm. We use an approximation similar to a recently developed scheme (critical minimum energy subspace). In this...
