Pion gas viscosity at low temperature and density
Antonio Dobado, Silvia N. Santalla
By using Chiral Perturbation Theory and the Uehling-Uhlenbeck equation we compute the viscosity of a pion gas, in the low temperature and low density regime, in terms of the temper…
Empirical calibration of the near-IR Ca II triplet - III. Fitting functions
A. J. Cenarro, J. Gorgas, N. Cardiel +2
Using a near-IR stellar library of 706 stars with a wide coverage of atmospheric parameters, we study the behaviour of the Ca II triplet strength in terms of effective temperature,…
Information and Computation: Classical and Quantum Aspects
A. Galindo, M. A. Martin-Delgado
Quantum theory has found a new field of applications in the realm of information and computation during the recent years. This paper reviews how quantum physics allows information…
Electron scattering on disordered double barrier GaAs-AlGaAs heterostructures
I. Gomez, E. Diez, F. Dominguez-Adame +1
We present a novel model to calculate vertical transport properties such as conductance and current in unintentionally disordered double barrier GaAs-AlGaAs heterostruc…
Misleading signatures of quantum chaos
J. M. G. Gomez, R. A. Molina, A. Relano +1
The main signature of chaos in a quantum system is provided by spectral statistical analysis of the nearest neighbor spacing distribution and the spectral rigidity given by $Δ_3(L)…
The Majorization Arrow in Quantum Algorithm Design
J. I. Latorre, M. A. Martin-Delgado
We apply majorization theory to study the quantum algorithms known so far and find that there is a majorization principle underlying the way they operate. Grover's algorithm is a n…
Chirally symmetric quark description of low energy π-πscattering
Pedro Bicudo, Stephen Cotanch, Felipe Llanes-Estrada +3
Weinberg's theorem for π-πscattering, including the Adler zero at threshold in the chiral limit, is analytically proved for microscopic quark models that preserve chiral symmetry.…
Scaling Solutions of Inelastic Boltzmann Equations with Over-populated High Energy Tails
M. H. Ernst, R. Brito
This paper deals with solutions of the nonlinear Boltzmann equation for spatially uniform freely cooling inelastic Maxwell models for large times and for large velocities, and the…
H alpha emitting galaxies and the star formation rate density at z~0.24
S. Pascual, J. Gallego, A. Aragon-Salamanca +1
We have carried out a survey searching for H alpha emitting galaxies at z~0.24 using a narrow band filter tuned with the redshifted line. The total sky area covered was 0.19 square…
Constructing Fresnel reflection coefficients by ruler and compass
J. J. Monzon, L. L. Sanchez-Soto
A simple and intuitive geometical method to analyze Fresnel formulas is presented. It applies to transparent media and is valid for perpendicular and parallel polarizations. The ap…
Chiral Perturbation Theory and the f2(1270) resonance
A. Dobado, J. R. Pelaez
Within Chiral Perturbation Theory, we study elastic pion scattering in the I=0, J=2, channel, whose main features are the f2(1270) resonance and the vanishing of the lowest order.…
Transients due to instabilities hinder Kardar-Parisi-Zhang scaling: a unified derivation for surface growth by electrochemical and chemical vapor deposition
Rodolfo Cuerno, Mario Castro
We propose a unified moving boundary problem for surface growth by electrochemical and chemical vapor deposition, which is derived from constitutive equations into which stochastic…
Velocity Tails for Inelastic Maxwell Models
Matthieu H. Ernst, Ricardo Brito
We study the velocity distribution function for inelastic Maxwell models, characterized by a Boltzmann equation with constant collision rate, independent of the energy of the colli…

The interplay between double exchange, super-exchange, and Lifshitz localization in doped manganites
J. L. Alonso, L. A. Fernandez, F. Guinea +2
Considering the disorder caused in manganites by the substitution of Mn by Fe or Ga, we accomplish a systematic study of doped manganites begun in previous papers. To this end, a d…
Stationary and Oscillatory Spatial Patterns Induced by Global Periodic Switching
J. Buceta, Katja Lindenberg, J. M. R. Parrondo
We propose a new mechanism for pattern formation based on the global alternation of two dynamics neither of which exhibits patterns. When driven by either one of the separate dynam…
Meson-meson scattering within one loop Chiral Perturbation Theory and its unitarization
A. Gomez Nicola, J. R. Pelaez
We present the complete one-loop calculation of all the two meson scattering amplitudes within the framework of SU(3) Chiral Perturbation Theory, which includes pions, kaons and th…
Quantum superintegrability and exact solvability in N dimensions
Miguel A. Rodriguez, Pavel Winternitz
A family of maximally superintegrable systems containing the Coulomb atom as a special case is constructed in N-dimensional Euclidean space. Two different sets of N commuting secon…
Complete meson-meson scattering within one loop in Chiral Perturbation Theory: Unitarization and resonances
J. R. Pelaez, A. Gomez Nicola
We review our recent one-loop calculation of all the two meson scattering amplitudes within SU(3) Chiral Perturbation Theory, i.e. with pions, kaons and etas. By unitarizing these…
