Beam-induced and cosmic-ray backgrounds observed in the ATLAS detector during the LHC 2012 proton-proton running period
2016
This paper discusses various observations on beam-induced and cosmic-ray backgrounds in the ATLAS detector during the LHC 2012 proton-proton run. Building on published results based on 2011 data, the correlations between background and residual pressure of the beam vacuum are revisited. Ghost charge evolution over 2012 and its role for backgrounds are evaluated. New methods to monitor ghost charge with beam-gas rates are presented and observations of LHC abort gap population by ghost charge are discussed in detail. Fake jets from colliding bunches and from ghost charge are analysed with improved methods, showing that ghost charge in individual radio-frequency buckets of the LHC can be resol…

Dynamics of a harmonic oscillator coupled with a Glauber amplifier
2020
A system of a quantum harmonic oscillator bi-linearly coupled with a Glauber amplifier is analysed considering a time-dependent Hamiltonian model. The Hilbert space of this system may be exactly subdivided into invariant finite dimensional subspaces. Resorting to the Jordan-Schwinger map, the dynamical problem within each invariant subspace may be traced back to an effective SU(2) Hamiltonian model expressed in terms of spin variables only. This circumstance allows to analytically solve the dynamical problem and thus to study the exact dynamics of the oscillator-amplifier system under specific time-dependent scenarios. Peculiar physical effects are brought to light by comparing the dynamics…
«A vós qui sou la bella i alta rima» (Els participants en la ‘Resposta’ trobada de Miquel Ortigues)
2021
En el marc de la realització de la tesi doctoral sobre el notari valencià Miquel Ortigues, hem estudiat l’obra atribuïda així com qüestions d’aspectes biogràfics i contextuals. En aquest article ens centrem en la importància de l’aparició d’una composició inèdita trobada en els seus protocols notarials i una revisió sobre la magnitud del personatge a partir de les relacions literàries que s’expliciten en els versos. L’article representa un nou enfocament sobre Miquel Ortigues que té en compte dades empíriques recollides als arxius. De forma col·lateral també significa la irrupció d’altres dos poetes, Ausiàs Crespí de Valldaura i Joan Ram Escrivà en el panorama poètic de les preguntes i resp…
L’estètica emocional de la transformació: una revisitació barroca de la Faula d’Apol·lo i Dafne
2021
The well-known Sonnet XIII by Garcilaso de la Vega «A Dafne ya los brazos le crecían» was to establish the disconsolate figure of Apollo, pining for the loss of Daphne, as the literary paradigm of the pangs of love —at least in Renaissance literature in the Iberian peninsula. Thus, a century later, Francesc Fontanella revisited the Garcilaso sonnet and carried out a profoundly Baroque re-reading. The Catalan text ‘transforms’ the symmetry and order in which the Spanish sonnet describes the metamorphosis of the nymph into an inseparable amalgam between the old way of being and the new reality, between the human and the plant, and freezes the figure in mutation: neither the original form nor …
Il libro del cortegiano del conte Baldassar Castiglione
Treatise describing the qualities of the perfect courtier through a conversation between renowned personalities, depicting at the same time an ideal model of sixteenth-century court society.
