S ep 1 99 9 Effective and asymptotic critical exponents of weakly diluted quenched Ising model : 3 d approach versus √ ε – expansion
Effective and asymptotic critical exponents of weakly diluted quenched Ising model: 3d approach versus √ ε–expansion Abstract We present a field-theoretical treatment of the critical behavior of three-dimensional weakly diluted quenched Ising model. To this end we analyse in a replica limit n → 0 5–loop renormalization group functions of the φ 4 –theory with O(n)– symmetric and cubic interactio...
متن کاملIsing Exponents in the Two-dimensional Site-diluted Ising Model
We study the site-diluted Ising model in two dimensions with Monte Carlo simulations. Using nite-size scaling techniques we compute the critical exponents observing deviations from the pure Ising ones. The diierences can be explained as the eeects of logarithmic corrections, without requiring to change the Universality Class.

متن کاملCritical exponents from five-loop strong-coupling φ4-theory in 4 − ε dimensions
Recently, one of us [1, 2] has developed a new approach to critical exponents of field theories based on the strong-coupling limit of variational perturbation expansions [3] and [4]3. This limit is relevant for critical phenomena if the renormalization constants are expressed in terms of the unrenormalized coupling constant. The theory was first applied successfully to O(N)symmetric φ4-theories...
