Méndez Martín, Bianchi ; Domínguez-Adame Acosta, Francisco ; Maciá Barber, Enrique Alfonso | IOP publishing ltd | 1993-01-07We show that the discretized forms of the Schrodinger and the Dirac equations for an arbitrary potential in one dimension are equivalent to the Poincare map of the corresponding wave equation for an array of delta-function potentials. Therefore,[...]texto impreso
Vodola, Davide ; Amaro, David ; Martín-Delgado Alcántara, Miguel Ángel ; Mülller, Markus | IOP publishing ltd | 2018-08-06In this Letter, we establish and explore a new connection between quantum information theory and classical statistical mechanics by studying the problem of qubit losses in 2D topological color codes. We introduce a protocol to cope with qubit lo[...]texto impreso
Magnetism of capped nanoparticles, NPs, of non- magnetic substances as Au and ZnO is briefly reviewed. The source of the magnetization is discussed on the light of recent X-ray magnetic circular dichroism experiments. As magnetic dichroism analy[...]texto impreso
Two novel classes of many-body models with nonlinear interactions 'of goldfish type' are introduced. They are solvable provided the initial data satisfy a single constraint (in one case; in the other, two constraints), i.e., for such initial dat[...]texto impreso
Zamorano Calvo, Jaime ; Gallego Maestro, Jesús ; Rego Fernández, Manuel ; Vitores, A. G. ; González Riestra, R. | IOP publishing ltd | 1992-09Multiwavelength observations of the galaxy UCM 2257+2438 found in the Universidad Complutense of Madrid (UCM) objective-prism survey are reported. The optic spectroscopy, CCD imaging, near-infrared and IRAS photometric data suggest that this obj[...]texto impreso
In the paper under review, the authors show that some specific graded Lie superalgebras could induce specific quartic extensions of Lie algebras. Such construction is then applied to show that it can be associated naturally a quartic extension o[...]texto impreso
Muñoz, M. C. ; Chico, L. ; López-Sancho, M. P. ; Beltrán Finez, Juan Ignacio ; Gallego, S. ; Cerdá, J. | IOP publishing ltd | 2006The symmetry underlying the geometric structure of materials determines most of their physical properties. In low dimensional systems the role of symmetry is enhanced and can give rise to new phenomena. Here, we report on unexpected magnetism in[...]texto impreso
The capabilities of SEAM in uniformity assessment of SI GaAs are investigated. Profiles of SEAM signals across the wafer and SEAM images of dislocation distribution are obtained. Part of the nonlinear signal shows a profile that is not related t[...]texto impreso
Mártil de la Plaza, Ignacio ; García Hemme, Eric ; González Díaz, Germán ; Olea Ariza, Javier ; Prado Millán, Álvaro del | IOP publishing ltd | 2011-11-09We assess the degree of crystallinity by means of UV and visible Raman scattering measurements of Ti implanted Si layers with very high doses (10(15)-5 x 10(16) cm(-2)) subsequently annealed by nanosecond pulsed laser melting (PLM). We obtain ul[...]texto impreso
Giménez, A. ; Ballester, J. L. ; Reglero, V. ; Fernández Figueroa, María José ; Castro Rubio, Elisa de | IOP publishing ltd | 1986-07Simultaneous uvby and H? photometry of thee noneclipsing double-lined spectroscopic binary TZ CrB, an active binary system with almost unevolved components, is presented. A small amplitude distortion wave (0.012 mag in y) has been found with max[...]texto impreso
The vectorial extension of the Ribaucour transformation for the Lame equations bf orthogonal conjugate nets in multidimensions is given. We show that the composition of two vectorial Ribaucour transformations with appropriate transformation data[...]texto impreso
Barrio Uña, Juan Abel ; Bonnefoy, Simon Francois Albert ; Contreras González, José Luis ; Dominguez, A. ; Fidalgo, D. ; Fonseca González, Mª Victoria ; López, M. ; Nievas Rosillo, Mireia | IOP publishing ltd | 2016-11We describe and report the status of a neutrino-triggered program in IceCube that generates real-time alerts for gamma-ray follow-up observations by atmospheric-Cherenkov telescopes (MAGIC and VERITAS). While IceCube is capable of monitoring the[...]texto impreso
Grigera, T.S. ; Martín Mayor, Víctor ; Parisi, G. ; Verrocchio, P. | IOP publishing ltd | 2002-03-11We study numerically and analytically a simple off-lattice model of scalar harmonic vibrations by means of Euclidean random matrix theory. Since the spectrum of this model shares the most puzzling spectral features with the high-frequency domain[...]texto impreso
Given a semidirect product g = s ? r of semisimple Lie algebras s and solvable algebras r, we construct polynomial operators in the enveloping algebra U(g) of g that commute with r and transform like the generators of s, up to a functional facto[...]texto impreso
Nogales Díaz, Emilio ; Garcia, J. A. ; Méndez Martín, Bianchi ; Piqueras de Noriega, Javier ; Lorenz, K. ; Alves, E. | IOP publishing ltd | 2008-03-20The luminescence properties of Er doped ?-Ga_2O_3 and of the erbium gallium garnet Er_3 Ga_5O_12(ErGG) have been investigated both in the visible and in the infrared (IR) ranges by means of photoluminescence (PL). Doping of the ?-Ga_2O_3 was obt[...]
