Strong-disorder fixed point in the dissipative random transverse-field Ising model.
The interplay between disorder, quantum fluctuations, and dissipation is studied in the random transverse Ising chain coupled to a dissipative Ohmic bath with a real space renormalization group. A typically very large length scale L* is identified above which the physics of frozen clusters dominates. Below L* a strong-disorder fixed point determines scaling at a pseudocritical point. In a Griff...
متن کاملStrong disorder fixed points in the two-dimensional random-bond Ising model
The random-bond Ising model on the square lattice has several disordered critical points, depending on the probability distribution of the bonds. There are a finite-temperature multicritical point, called Nishimori point, and a zerotemperature fixed point, for both a binary distribution where the coupling constants take the values ±J and a Gaussian disorder distribution. Inclusion of dilution i...
متن کاملStability of a fixed point in the replica action for the random field Ising model
Abstract. We reconsider stability of the non-trivial fixed point in 6− ǫ dimensional effective action for the random field Ising model derived by Brézin and De Dominicis. After expansion parameters of physical observables are clarified, we find that the nontrivial fixed point in 6 − ǫ dimensions is stable, contrary to the argument by Brézin and De Dominicis. We also computed the exponents ν and...
متن کاملRandom Current Representation for Transverse Field Ising Model
Random current representation (RCR) for transverse field Ising models (TFIM) has been introduced in [15]. This representation is a space-time version of the classical RCR exploited by Aizenman et. al. [1, 3, 4]. In this paper we formulate and prove corresponding space-time versions of the classical switching lemma and show how they generate various correlation inequalities. In particular we pro...
متن کاملMagnetic Properties in a Spin-1 Random Transverse Ising Model on Square Lattice
In this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4), ferromagnetic Ising system consisting of magnetic atoms with spin-1. This study is done using the effectivefield theory (EFT) with correlations method. The equations are derived using...
