Rough Interfaces Beyond the Gaussian Approximation

We compare predictions of the Capillary Wave Model beyond its Gaussian approximation with Monte Carlo results for the energy gap and the surface energy of the 3D Ising model in the scaling region. Our study reveals that the finite size effects of these quantities are well described by the Capillary Wave Model, expanded to two–loop order (one order beyond the Gaussian approximation).

Quantum dynamics beyond the Gaussian approximation.

The time dependent quantum variational principle is emerging as an important means of studying quantum dynamics, particularly in early universe scenarios. To date all investigations have worked within a Gaussian framework. Here we present an improved method which is demonstrated to be superior to the Gaussian approach and may be naturally extended to the eld{theoretic case.

Accusation probabilities in Tardos codes: beyond the Gaussian approximation

We study the probability distribution of user accusations in the q-ary Tardos fingerprinting system under the Marking Assumption, in the restricted digit model. In particular, we look at the applicability of the so-called Gaussian approximation, which states that accusation probabilities tend to the normal distribution when the fingerprinting code is long. We introduce a novel parametrization o...

Propagation of Hermite-Gaussian and Laguerre-Gaussian beams beyond the paraxial approximation.

On the basis of the vectorial Rayleigh-Sommerfeld formulas and by means of the relation between Hermite and Laguerre polynomials, the analytical expressions for the propagation of the Hermite-Gaussian (HG) and Laguerre-Gaussian (LG) beams beyond the paraxial approximation are derived, with the corresponding far-field propagation expressions and that for the Gaussian beams being given as special...

Micromechanics of Rough Interfaces

The mechanical behavior of rough interfaces is modeled from a micromechanical viewpoint. A kinematically driven mechanistic approach is adopted which explicitly considers the interaction of asperities on the fracture surface. The mating asperities are assumed to behave in accordance with contact mechanics postulates of non-conforming bodies. The roughness of the fracture surface is represented ...
