Nematic phase in the J(1)-J(2) square-lattice Ising model in an external field.
The J(1)-J(2) Ising model in the square lattice in the presence of an external field is studied by two approaches: the cluster variation method (CVM) and Monte Carlo simulations. The use of the CVM in the square approximation leads to the presence of a new equilibrium phase, not previously reported for this model: an Ising-nematic phase, which shows orientational order but not positional order,...
متن کاملStructure Factor of the Random Field Ising Model
-Using Monte Carlo simulations, we studied the structure factor S (q) of the two-dimensional (2D) random field Ising model (RFIM) with a binary probability distribution. We observe that S (q) changes its lineshape from Lorentzian to a Lorentzian-three half form, ( L R Z ) ~ / ~ as the random field and temperature are lowered. The time dependent structure factor S (q, t ) after a quench from a p...
متن کاملPoissonian Behavior of Ising Spin Systems in an External Field
We apply the Stein-Chen method for Poisson approximation to spin-half Isingtype models, in positive external eld, which satisfy the FKG inequality. In particular we show that, provided the density of minus spins is low and can be expanded as a convergent power series in the activity (fugacity) variable, the distribution of minus spins is approximately Poisson. The error of the approximation is ...
متن کاملLattice Ising Model in a Field: E8 Scattering Theory
Zamolodchikov found an integrable field theory related to the Lie algebra E8, which describes the scaling limit of the Ising model in a magnetic field. He conjectured that there also exist solvable lattice models based on E8 in the universality class of the Ising model in a field. The dilute A3 model is a solvable lattice model with a critical point in the Ising universality class. The paramete...
