Formation of a Nematic Fluid at High Fields in Sr3Ru2O7
R. A. Borzi, S. A. Grigera, J. Farrell +6
In principle, a complex assembly of strongly interacting electrons can self-organise into a wide variety of collective states, but relatively few such states have been identified i…
Cationic exchange in nanosized ZnFe2O4 spinel revealed by experimental and simulated near-edge absorption structure
S. J. Stewart, S. J. A. Figueroa, J. M. Ramallo-López +4
The non-equilibrium cation site occupancy in nanosized zinc ferrites (6-13 nm) with different degree of inversion (0.2 to 0.4) was investigated using Fe and Zn K-edge x-ray absorpt…
The emergence of AdS(2) from quantum fluctuations
J. Ambjorn, R. Janik, W. Westra +1
We have shown how the quantization of two-dimensional quantum gravity with an action which contains only a positive cosmological constant and boundary cosmological constants leads…
On Dalgarno and Lewis Perturbation Theory for Scattering States
Paolo Amore, Francisco M. Fernandez
We apply the method of Dalgarno and Lewis to scattering states and discuss the choice of the unperturbed model in order to have a convergent perturbation series for the phase shift…
Variational collocation on finite intervals
Paolo Amore, Mayra Cervantes, Francisco M. Fernández
In this paper we study a new family of sinc--like functions, defined on an interval of finite width. These functions, which we call ``little sinc'', are orthogonal and share many o…
Monte Carlo simulation of the irreversible growth of magnetic thin films
Julián Candia, Ezequiel V. Albano
The growth of magnetic films with ferromagnetic interactions between nearest-neighbor spins is studied in dimensional rectangular geometries for . Magnetic films a…
Mosaic multi-state scenario vs. one-state description of supercooled liquids
Andrea Cavagna, Tomas S. Grigera, Paolo Verrocchio
According to the mosaic scenario, relaxation in supercooled liquids is ruled by two competing mechanisms: surface tension, opposing the creation of local excitations, and entropy,…
Application of the Asymptotic Iteration Method to a Perturbed Coulomb Model
Paolo Amore, Francisco M. Fernandez
We show that the asymptotic iteration method converges and yields accurate energies for a perturbed Coulomb model. We also discuss alternative perturbation approaches to that model…
Critical Behavior of an Ising System on the Sierpinski Carpet: A Short-Time Dynamics Study
M. A. Bab, G. Fabricius, E. V. Albano
The short-time dynamic evolution of an Ising model embedded in an infinitely ramified fractal structure with noninteger Hausdorff dimension was studied using Monte Carlo simulation…
Topological Effects caused by the Fractal Substrate on the Nonequilibrium Critical Behavior of the Ising Magnet
M. A. Bab, G. Fabricius, E. V. Albano
The nonequilibrium critical dynamics of the Ising magnet on a fractal substrate, namely the Sierpinski carpet with Hausdorff dimension =1.7925, has been studied within the sh…
Experimental evidence on the development of scale invariance in the internal structure of self-affine aggregates
C. M. Horowitz, M. A. Pasquale, E. V. Albano +1
It is shown that an alternative approach for the characterization of growing branched patterns consists of the statistical analysis of frozen structures, which cannot be modified b…
Dynamic properties in a family of competitive growing models
Claudio M. Horowitz, Ezequiel V. Albano
The properties of a wide variety of growing models, generically called , are studied by means of numerical simulations and analytic developments. The study comprises the foll…
