Anisotropic scaling in layered aperiodic Ising systems
The influence of a layered aperiodic modulation of the couplings on the critical behaviour of the two–dimensional Ising model is studied in the case of marginal perturbations. The aperiodicity is found to induce anisotropic scaling. The anisotropy exponent z, given by the sum of the surface magnetization scaling dimensions, depends continuously on the modulation amplitude. Thus these systems ar...
متن کاملDisentangling Scaling Properties in Anisotropic and Inhomogeneous Turbulence
We address scaling in inhomogeneous and anisotropic turbulent flows by decomposing structure functions into their irreducible representation of the SO(3) symmetry group which are designated by j, m indices. Employing simulations of channel flows with Rel ø 70 we demonstrate that different components characterized by different j display different scaling exponents, but for a given j these remain...
متن کاملQuantum phase transitions and thermodynamic properties in highly anisotropic magnets
The systems exhibiting quantum phase transitions (QPT) are investigated within the Ising model in the transverse field and Heisenberg model with easy-plane single-site anisotropy. Near QPT a correspondence between parameters of these models and of quantum φ 4 model is established. A scaling analysis is performed for the ground-state properties. The influence of the external longitudinal magneti...
متن کاملElastic properties of highly anisotropic thin poly(propylene) foams
In this letter, elastic properties of highly anisotropic cellular poly(propylene) films are reported. The material shows peculiar elastic properties compared to other foams in the literature. The data is displayed as the relative Young’s modulusE∗/Es versus relative density ρ∗/ρs. Almost all the data from the literature are located on the region E∗/Es = (ρ ∗/ρs) n with 1 ≤ n ≤ 6. The introduced...
متن کاملAnisotropic scaling of magnetohydrodynamic turbulence.
We present a quantitative estimate of the anisotropic power and scaling of magnetic field fluctuations in inertial range magnetohydrodynamic turbulence, using a novel wavelet technique applied to spacecraft measurements in the solar wind. We show for the first time that, when the local magnetic field direction is parallel to the flow, the spacecraft-frame spectrum has a spectral index near 2. T...
