Recently extended precise numerical methods and droplet scaling arguments allow for a coherent picture of the glassy states of two-dimensional Ising spin glasses to be assembled. The length scale at which entropy becomes important and produces “chaos”, the extreme sensitivity of the state to temperature, is found to depend on the type of randomness. For the ±J model this length scale dominates the low-temperature specific heat. Although there is a type of universality, some critical exponents… CONTINUE READING
