Álvarez Galindo, Gabriel ; Martínez Alonso, Luis ; Medina Reus, Elena | Elsevier Science BV | 2011-07-11We present a method to compute the genus expansion of the free energy of Hermitian matrix models from the large N expansion of the recurrence coefficients of the associated family of orthogonal polynomials. The method is based on the Bleher-Its [...]texto impreso
Álvarez Galindo, Gabriel ; Biondi, Biondo ; Guitton, Antoine | Soc Exploration Geophysicists | 2007-09In complex areas, the attenuation of specular and diffracted multiples in image space is an attractive alternative to surface-related multiple elimination (SRME) and to data space Radon filtering. We present the equations that map, via wave-equa[...]texto impreso
We give an exhaustive characterization of the complex saddle point configurations of the Gross-WittenWadia matrix model in the large-N limit. In particular, we characterize the cases in which the saddles accumulate in one, two, or three arcs, i[...]texto impreso
Álvarez Galindo, Gabriel ; Martínez Alonso, Luis ; Medina Reus, Elena | 2013-06This paper deals with the determination of the S-curves in the theory of non-hermitian orthogonal polynomials with respect to exponential weights along suitable paths in the complex plane. It is known that the corresponding complex equilibrium p[...]texto impreso
Sebastián Franco, José Luis ; Muñoz San Martín, Sagrario ; Sancho Ruíz, Miguel ; Álvarez Galindo, Gabriel ; Miranda Pantoja, José Miguel | IOP publishing ltd | 2007-12-07We have studied the influence of the anisotropic and dispersive nature of the red blood cell structure on the energy absorption and electric field distribution within the cell exposed to electromagnetic fields of frequencies in the range from 50[...]texto impreso
Sebastián Franco, José Luis ; Muñoz San Martín, Sagrario ; Sancho Ruíz, Miguel ; Martínez López, Genoveva ; Álvarez Galindo, Gabriel | American Physical Society | 2011-07-28We use the Maxwell stress tensor to calculate the dielectrophoretic force and electrorotational torque acting on a realistic four-shelled model of the yeast Saccharomyces cerevisiae in a nonuniform rotating electric field generated by four copla[...]texto impreso
Sebastián Franco, José Luis ; Muñoz San Martín, Sagrario ; Sancho Ruíz, Miguel ; Miranda Pantoja, José Miguel ; Álvarez Galindo, Gabriel | American Physical Society | 2005-09We study the influence of an external electromagnetic field of 1.8 GHz in the formation or disaggregation of long rouleau of identical erythrocyte cells. In particular we calculate the variation of the transmembrane potential of an individual er[...]texto impreso
A very important aspect of removing multiples from seismic data is accurate prediction of their kinematics. We cast the multiple prediction problem as an operation in the image space parallel to the conventional surface-related multiple-predicti[...]texto impreso
Numerical simulations are performed for isolated cyclic, or ring, chains with excluded volume. Data are reported for the form factor, S(x), where x is the reduced scattering variable, and also for averages and distributions of the distance betwe[...]texto impreso
Álvarez Galindo, Gabriel ; Martínez Alonso, Luis ; Medina Reus, Elena | IOP publishing ltd | 2011-07-15We present a method to characterize and compute the large N formal asymptotics of regular and critical Hermitian matrix models with general even potentials in the one-cut and two-cut cases. Our analysis is based on a method to solve continuum li[...]texto impreso
Valdés, Jorge ; Román, Domingo ; Álvarez Galindo, Gabriel ; Ortlieb, Luc ; Guiñez, Marcos | Elsevier Science BV | 2008-05Physical-chemical parameters (temperature, salinity, dissolved oxygen, nutrients, and chlorophyll concentration) of surface waters were used to evaluate the influence of biological and physical processes over the metal concentrations (Cd, Ni, V,[...]texto impreso
Álvarez Galindo, Gabriel ; Belanger, D.P. ; Durand, A.M. ; Martín Mayor, Víctor ; Montoya, K. ; Muro, Y. | American Physical Society | 2012-07-12The low temperature excitations in the anisotropic antiferromagnetic Fe_(x)Zn_(1-x)F_(2) for x = 0.25 and 0.31, at and just above the magnetic percolation threshold concentration x_(p) = 0.25, were measured using inelastic neutron scattering. Th[...]texto impreso
We present a method to sum Borel- and Gevrey-summable asymptotic series by matching the series to be summed with a linear combination of asymptotic series of known functions that themselves are scaled versions of a single, appropriate, but other[...]texto impreso
We present an implementation of the method of orthogonal polynomials which is particularly suitable to study the partition functions of Penner random matrix models, to obtain their explicit forms in the exactly solvable cases, and to determine [...]texto impreso
Álvarez Galindo, Gabriel ; Martínez Alonso, Luis ; Medina Reus, Elena | IOP publishing ltd | 2017-03-24The partition function of the Penner matrix model for both positive and negative values of the coupling constant can be explicitly written in terms of the Barnes G function. In this paper we show that for negative values of the coupling constant[...]
