Stiffness of the Edwards-Anderson model in all dimensions.
نویسنده
چکیده
A comprehensive description in all dimensions is provided for the scaling exponent y of low-energy excitations in the Ising spin glass introduced by Edwards and Anderson. A combination of extensive numerical as well as theoretical results suggest that its lower critical dimension is exactly dl=5/2. Such a result would be an essential feature of any complete theory of low-temperature spin glass order and imposes a constraint that may help to distinguish between theories.

Reduction of two-dimensional dilute Ising spin glasses
The recently proposed reduction method is applied to the Edwards-Anderson model on bond-diluted square lattices. In combination with a graph-theoretical matching algorithm, this allows us to calculate numerically exact ground states of large systems. Low-temperature domain-wall excitations are studied to determine the stiffness exponent y2. A value of y2=−0.281 3 is found, consistent with previ...

متن کاملSome aspects of infinite range models of spin glasses: theory and numerical simulations
The expression " spin glasses " was originally coined to describe metallic alloys of a non-magnetic metal with few, randomly substituted, magnetic impurities. Experimental evidences where obtained for a low temperature " spin-glass " phase characterized by a non-periodic freezing of the magnetic moments (the spins) with a very slow, and strongly history dependent, response to external perturbat...
متن کاملMulti-overlap simulations of free-energy barriers in the 3D Edwards–Anderson Ising spin glass
We report large-scale simulations of the three-dimensional Edwards–Anderson Ising spin-glass model using the multi-overlap Monte Carlo algorithm. We present our results in the spin-glass phase on free-energy barriers and the non-trivial finite-size scaling behavior of the Parisi order-parameter distribution. 1999 Elsevier Science B.V.
