Damage Spreading in the Ising Model
نویسندگان
چکیده
We present two new results regarding damage spreading in ferromagnetic Ising models. First, we show that a damage spreading transition can occur in an Ising chain that evolves in contact with a thermal reservoir. Damage heals at low temperature and spreads at high T . The dynamic rules for the system’s evolution for which such a transition is observed are as legitimate as the conventional rules (Glauber, Metropolis, heat bath). Our second result is that such transitions are not always in the directed percolation universality class. PACS numbers: 05.50.q, 05.70.Ln, 64.60.Ak, 64.60.Ht Typeset using REVTEX 1

Time-Dependent Thermodynamic Properties of the Ising Model from Damage Spreading
The relationship between damage spreading and static thermodynamic properties in the Ising model developed by Coniglio et al. is here extended to include time-dependent thermodynamic quantities. We exploit this new result to measure the time-dependent spin correlation function from damage spreading in the Ising model with heat bath and Glauber dynamics. Until now, only static thermodynamic quan...
متن کاملDamage Spreading in the Kawasaki Ising Model
We observe no phase transition in the damage spreading probability at the Curie point of the 2D Ising model with nearest neighbor spin exchange dynamics. Furthermore, we report values of the growth exponent z close to unity, implying "'speed of light" transmission of information, and values of the exponents describing the scaling behavior of the damage mass with time and distance, close to two....
متن کاملDamage spreading in small world Ising models.
We study damage spreading in the ferromagnetic Ising model on small world networks using Monte Carlo simulation with Glauber dynamics. The damage spreading temperature T(d) is determined as a function of rewiring probability p for small world networks obtained by rewiring the two-dimensional square and three dimensional cubic lattices. We find that the damage for different values of p collapse ...
متن کاملAre Damage Spreading Transitions Generically in the Universality Class of Directed Percolation?
We present numerical evidence for the fact that the damage spreading transition in the Domany-Kinzel automaton found by Martins et al. is in the same universality class as directed percolation. We conjecture that also other damage spreading transitions should be in this universality class, unless they coincide with other transitions (as in the Ising model with Glauber dynamics) and provided the...
متن کاملDamage spreading in Ising model with increased range of interaction
2014 We have studied the spreading of damage in Ising models with increased range of interaction. Simulating a square lattice of linear size 1000 we find that the spreading temperature and the Curie temperature of magnetic transition are the same for both nearest and next nearest neighbour models whereas for third nearest neighbour model they may not be the same.
