Lorentz invariance and gauge equivariance
2014
Trying to place Lorentz and gauge transformations on the same foundation, it turns out that the first one generates invariance, the second one equivariance, at least for the abelian case. This similarity is not a hypothesis but is supported by and a consequence of the path integral formalism in quantum field theory.
De piscibus et aquatilibus libelli III novi (Zürich 1556) Ein bisher unbeachtetes zoologisches Werk von Conrad Gesner
1990
Conrad Gesner was one of the main representatives of Renaissance-Humanism. Although having great respect for the knowledge handed down by classical antiquity, he combined his studies of the ancient authors with empirical knowledge obtained by immediate observation of nature. His most famous work was the great „Historia animalium”, a comprehense encyclopedia of zoology. Preparing this main zoological work Gesner wrote a small book about fishes „De piscibus et aquatilibus libri III novi” (1556), through which it is possible to gain a deep insight into Gesner's preparatory work and method.
El auto sacramental y la alegorización de la historia: "El socorro de Cádiz" de Juan Pérez de Montalbán
2012
Este trabajo estudia la relación excepcional entre acontecimientos históricos y género sacramental, a partir de un auto que se dio por perdido durante bastantes años. Se trata de El socorro de Cádiz de Juan Pérez de Montalbán en el que se alegoriza la defensa de Cádiz contra los ingleses en 1625. This paper analyzes the exceptional relationship between historical events and the sacramental genre, based on an «auto» that was considered lost during many years. This «auto» is El socorro de Cádiz by Juan Pérez de Montalbán, in which the playwright allegorizes the defense of Cádiz against the English in 1625.
La esclava del cielo, Santa Engracia, una comedia olvidada de Andrés de Claramonte
2009
La esclava del cielo, Santa Engracia, a forgotten play by Andrés de Claramonte Two are the objectives of this paper: in the first place, to elucidate the relationship that exists between the manuscript copy that has been preserved of a play entitled La esclava del cielo, Santa Engracia and the play of the same title that is mentioned in several documents of the 17th Century related to the professional companies of the autores Cristóbal Ortiz, Juan Bautista Valenciano and Juan Jerónimo Valenciano. In the second place, to critically analyze the attribution of La esclava del cielo, Santa Engracia to the playwright Andrés de Claramonte that appears in several of these documents, both by assessi…
Thouless-Valatin moment of inertia and removal of the spurious mode in the linear response theory
2020
Symmetry breaking at the mean-field level leads to an appearance of a symmetry restoring Nambu-Goldstone (NG) mode in the linear response theory. These modes represent a special kind of collective motion of the system. However, they can interfere with the calculated intrinsic physical excitations and, hence, they are often called as spurious modes. I discuss translational and rotational NG mode and the inertia parameter associated with these modes, by using the finite amplitude method formalism. I will also discuss how to remove spurious mode from the calculated transition strength function.
On the thermal instability in a horizontal rectangular porous channel heated from below by a constant flux
2014
Published version of an article in the journal: Journal of Physics: Conference Series. Also available from the publisher at: http://dx.doi.org/10.1088/1742-6596/501/1/012003 Open Access The onset of thermoconvective instability in a rectangular horizontal channel filled with a fluid-saturated porous medium is studied. The channel is heated from below with a constant flux. The top wall is maintained at a uniform constant temperature, while the lateral boundaries are permeable and perfectly conducting. The stability of the basic motionless state is analysed with respect to small-amplitude disturbances. The eigenvalue problem for the neutral stability condition is solved analytically for the n…
Las pullas de Isabel(a) entre Lope y Góngora : modelos, versos y paratextos de 'Virtud, pobreza y mujer'
2021
Este artículo se ha beneficiado de mi participación en los proyectos de investigación PGC2018-094395-BI00, financiado por el Ministerio de Ciencia, Innovación y Universidades, PID2019-104045GB-C54 y PID2019-104045GB-C51, financiados por el Ministerio de Ciencia e Innovación y por fondos FEDER. El presente artículo aborda la relación entre dos comedias: Las firmezas de Isabela, de Luis de Góngora, y Virtud, pobreza y mujer, de Lope de Vega. Tras fijar la fecha de escritura de la segunda, se estipula que fue Lope quien pudo inspirarse en Góngora y no al revés (cuestión discutida), y se aclaran, amplían, matizan o desmienten las huellas de la comedia gongorina atisbadas hasta ahora por la crít…
Èsquil al Curial e Güelfa
2018
Resum: El llibre III de la novel.la pre-renaixentista Curial e Guelfa presenta les característiques d’una prosa deutora en un alt grau de l’humanisme. Elements destacats en són la dicció mitològica, la ubicació de part dels esdeveniments i la imitació de models literaris clàssics. Al present treball mirem d’escatir fins a quin punt la tragèdia d’Èsquil on es representava el judici d’Orestes, les Eumènides, ha pogut esdevenir el model per al judici de Curial al Parnàs, com anys enrera va proposar Patricia Boehne. D’acord amb unes premisses metodològiques diferents de les d’ella, basem les nostres conclusions en les relacions intertextuals establertes entre ambdues obres.

Rei publicae Romanae auctor : la construction du mythe de Lucius Junius Brutus à l’époque impériale
2023
Un archétype au service des idées républicaines Dans sa dissertation académique consacrée à la figure de Lucius Junius Brutus, au début du xviiie siècle, Christoph Ludwig Crell, un juriste érudit habitué à travailler sur l’histoire et le droit des Romains, n’hésitait pas à caractériser ce personnage comme le fondateur de la république romaine : rei publicae Romanae auctor. Revalorisant des témoignages antiques, et avant tout les récits de Tite-Live et Denys d’Halicarnasse, sur le rôle de prem...
Sobre la presència de Boccaccio en el Curial e Güelfa: la novella X.8
2013
Resum: Les darreres investigacions sobre la novel·la cavalleresca catalana Curial e Guelfa subratllen de forma unanime la qualitat literaria de l’obra i la riquesa de la cultura literaria del seu autor, en especial en relacio als autors classics i italians. Entre els italians, nombrosos estudiosos han remarcat el paper cabdal de Boccaccio, i en particular del Decameron , com a model d’escriptura i com a intermediari de la tradicio classica, per a l’autor anonim catala. En aquest treball oferim una mostra de la presencia de la novella X.8 en el text catala, tot resseguint ambdues narracions, i observant l’encaix en el nou context narratiu que duu a terme l’autor anonim del Curial . Aixo ens …
