Relaxation at finite temperature in Fully-Frustrated Ising Models

چکیده
We consider by means of Monte Carlo simulations the relaxation in the paramagnetic phase of the anti-ferromagnetic Ising model on a triangular lattice and of a fully-frustrated Ising model on a square lattice. In contradistinction to previous studies of the second model, we show that spin-spin correlation functions do not decay with a stretched-exponential law at low temperature but that both models display an exponential decay with logarithmic corrections that are interpreted as the signature of topological defects.

Precursor phenomena in frustrated systems.
To understand the origin of the dynamical transition, between high-temperature exponential relaxation and low-temperature nonexponential relaxation, that occurs well above the static transition in glassy systems, a frustrated spin model, with and without disorder, is considered. The model has two phase transitions, the lower being a standard spin glass transition (in the presence of disorder) o...
متن کاملTwo phase transitions in the fully frustrated XY model.
The fully frustrated XY model on a square lattice is studied by means of Monte Carlo simulations. A Kosterlitz-Thouless transition is found at TKT ≈ 0.446, followed by an ordinary Ising transition at a slightly higher temperature, Tc ≈ 0.452. The non-Ising exponents reported by others, are explained as a failure of finite size scaling due to the screening length associated with the nearby Koste...

We study the dynamics of the critical two-dimensional fully-frustrated Ising model by means of Monte Carlo simulations. The dynamical exponent is estimated at equilibrium and is shown to be compatible with the value zc = 2. In a second step, the system is prepared in the paramagnetic phase and then quenched at its critical temperature Tc = 0. Numerical evidences for the existence of logarithmic...
متن کاملMulticritical behavior in the fully frustrated XY model and related systems
We study the phase diagram and critical behavior of the two-dimensional square-lattice fully frustrated XY model (FFXY) and of two related models, a lattice discretization of the Landau-Ginzburg-Wilson Hamiltonian for the critical modes of the FFXY model, and a coupled Ising-XY model. We present a finite-size-scaling analysis of the results of high-precision Monte Carlo simulations on square la...

We study the phase diagram of the two-dimensional fully frustrated XY model (FFXY) and of two related models, a lattice discretization of the Landau-Ginzburg-Wilson Hamiltonian for the critical modes of the FFXY model, and a coupled Ising-XY model. We present Monte Carlo simulations on square lattices L × L, L . 10. We show that the lowtemperature phase of these models is controlled by the same...
