Nonlocal low-energy effective action for gravity with torsion
Antonio Dobado, Antonio L. Maroto
In this work we calculate the low-energy effective action for gravity with torsion, obtained after the integration of scalar and fermionic matter fields, using the local momentum r…
Comment on ``Periodic wave functions and number of extended states in random dimer systems'
M. Hilke, J. C. Flores, F. Dominguez-Adame
There are no periodic wave-functions in the RDM but close to the critical energies there exist periodic envelopes. These envelopes are given by the non-disordered properties of the…
Darboux Transformations for SUSY Integrable Systems
Q. P. Liu, Manuel Manas
Several types of Darboux transformations for supersymmetric integrable systems such as the Manin-Radul KdV, Mathieu KdV and SUSY sine-Gordon equations are considered. We also prese…
Report of the Working Group on Goldstone Boson Production and Decay
J. Bijnens, G. Colangelo, G. D'Ambrosio +11
This is the summary of the working group on Goldstone Boson Production and Decay of the Chiral Dynamics Workshop in Mainz, September 1-5, 1997. For the production aspects we discus…
The Schwinger and Thirring models at finite chemical potential and temperature
Ramon F. Alvarez-Estrada, Angel Gomez Nicola
We study the generating functional for the massless Schwinger model in the torus, at nonzero chemical potential and temperature. The lack of hermiticity of the Dirac operator yield…
Equivalence of the Variational Matrix Product Method and the Density Matrix Renormalization Group applied to Spin Chains
J. Dukelsky, M. A. Martin-Delgado, T. Nishino +1
We present a rotationally invariant matrix product method (MPM) of isotropic spin chains. This allows us to deal with a larger number of variational MPM parameters than those consi…
Vectorial Ribaucour Transformations for the Lame Equations
Q. P. Liu, Manuel Manas
The vectorial extension of the Ribaucour transformation for the Lame equations of orthogonal conjugates nets in multidimensions is given. We show that the composition of two vector…
Analysis of factorization in (e,e'p) reactions: A survey of the relativistic plane wave impulse approximation
J. A. Caballero, T. W. Donnelly, E. Moya de Guerra +1
The issue of factorization within the context of coincidence quasi-elastic electron scattering is reviewed. Using a relativistic formalism for the entire reaction mechanism and res…
Spatial Correlations in Compressible Granular Flows
T. P. C. van Noije, M. H. Ernst, R. Brito
For a freely evolving granular fluid, the buildup of spatial correlations in density and flow field is described using fluctuating hydrodynamics. The theory for incompressible flow…
A lattice field theoretical model for high- superconductivity
J. L. Alonso, Ph. Boucaud, V. Martin-Mayor +1
We present a 2+1-dimensional lattice model for the copper oxide superconductors and their parent compounds, in which both the charge and spin degrees of freedom are treated dynamic…
Beryllium, Lithium and Oxygen Abundances in F-type Stars
R. J. Garcia Lopez, M. C. Dominguez Herrera, M. R. Perez de Taoro +4
Beryllium and oxygen abundances have been derived in a sample of F-type field stars for which lithium abundances had been measured previously, with the aim of obtaining observation…
Decoupling of supersymmetric particles
A. Dobado, M. J. Herrero, S. Peñaranda
The possibility of a heavy supersymmetric spectrum at the Minimal Supersymmetric Standard Model is considered and the decoupling from the low energy electroweak scale is analyzed i…
Comment on ``Experimental demonstration of the violation of local realism without Bell inequalities'' by Torgerson et al
Adan Cabello, Emilio Santos
We exhibit a local-hidden-variable model in agreement with the results of the two-photon coincidence experiment made by Torgerson et al. [Phys. Lett. A 204 (1995) 323]. The existen…
Quantum mechanics and elements of reality inferred from joint measurements
Adan Cabello, Guillermo Garcia-Alcaine
The Einstein-Podolsky-Rosen argument on quantum mechanics incompleteness is formulated in terms of elements of reality inferred from joint (as opposed to alternative) measurements,…
Finite-size scaling study of the d=4 site-diluted Ising
H. G. Ballesteros, L. A. Fernandez, V. Martin-Mayor +3
We study the four dimensional site-diluted Ising model using finite-size scaling techniques. We explore the whole parameter space (density-coupling) in order to determine the Unive…
Discrete Levy Transformations and Casorati Determinant Solutions of Quadrilateral Lattices
Q. P. Liu, Manuel Manas
Sequences of discrete Levy and adjoint Levy transformations for the multidimensional quadrilateral lattices are studied. After a suitable number of iterations we show how all the r…
8-Vertex Correlation Functions and Twist Covariance of q-KZ Equation
C. Fronsdal, A. Galindo
We study the vertex operators associated with standard quantum groups. The element is a "Casimir operator" for quantized Kac-Moody algebras and the quantum Kniz…
Multiwavelength optical observations of chromospherically active binary systems. II. EZ Pegasi
D. Montes, J. Sanz-Forcada, M. J. Fernandez-Figueroa +2
The star EZ Peg, long ago classified as cataclysmic variable, has been shown to be a chromospherically active binary system of the RS CVn-type. In this paper we have analysed, usin…
Integrating a Lexical Database and a Training Collection for Text Categorization
Jose Maria Gomez Hidalgo, Manuel de Buenaga Rodriguez
Automatic text categorization is a complex and useful task for many natural language processing applications. Recent approaches to text categorization focus more on algorithms than…
Proposed experimental tests of the Bell-Kochen-Specker theorem
Adan Cabello, Guillermo Garcia-Alcaine
For a two-particle two-state system, sets of compatible propositions exist for which quantum mechanics and noncontextual hidden-variable theories make conflicting predictions for e…
