Real-space renormalization group for the random-field Ising model.
We present real–space renormalization group (RG) calculations of the critical properties of the random–field Ising model on a cubic lattice in three dimensions. We calculate the RG flows in a two–parameter truncation of the Hamiltonian space. As predicted, the transition at finite randomness is controlled by a zero temperature, disordered critical fixed point, and we exhibit the universal cross...
متن کاملRenormalization-group study of the replica action for the random field Ising model
We reexamine the effective action for the d-dimensional random field Ising model derived by Brézin and De Dominicis. We find a non-Gaussian fixed point where the φ4 couplings in the action have various scaling dimensions. The correlation-length exponent in d = 6 − ǫ has the value consistent with the argument of the dimensional reduction in the leading order.
متن کاملRandom Geometries and Real Space Renormalization Group
A method of " blocking " triangulations that rests on the self-similarity feature of dynamically triangulated random manifolds is proposed and used to define the renormalization group for random geometries. As an illustration, the idea is applied to pure euclidean quantum gravity in 2d. Generalization to more complicated systems and to higher dimensionalities of space-time appears straightforwa...
متن کاملRenormalization Group and Random Systems
Some of the most interesting and challenging problems in theoretical and mathematical physics have been the ones involving in an essential way several distance scales. Such problems include the theory of critical phenomena and phase transitions, the problem of the existence of relativistic quantum field theories, the turbulent behaviour in hydrodynamic systems and many others. While many of the...
متن کاملReplica field theory for a polymer in random media
In this paper we revisit the problem of a (non-self-avoiding) polymer chain in a random medium which was previously investigated by Edwards and Muthukumar (EM) [J. Chem. Phys. 89, 2435 (1988)]. As noticed by Cates and Ball (CB) [J. Phys. (France) 49, 2009 (1988)] there is a discrepancy between the predictions of the replica calculation of EM and the expectation that in an infinite medium the qu...
