Arte Tedesca e Arte Degenerata. Aspetti della politica culturale del Terzo Reich

2011

Il saggio prende le mosse dalle iniziative intraprese da Joseph Goebbels nell'ambito dell'organizzazione culturale in Germania, durante i primi mesi del "nuovo corso" nazista. Fra i vari temi, vengono affrontate le questioni relative alle rapporto con la cultura della Repubblica di Weimar, alle grandi mostre di Monaco (Entartete Kunst, 1937) e Duesselforf (Entartete Musik, 1938), nonché della produzione musicale all'interno del ghetto di Theresienstadt.

Benedetto XVI e il compito urgente dell’educazione

2015

All’origine della riflessione sull’urgenza di una Nuova Evangelizzazione ci sta la constatazione di una diffusa situazione di crisi di valori cristiani e educativi, percepibili soprattutto nei Paesi di antica cristianità. Più volte, nei suoi discorsi, Benedetto XVI concentra l’attenzione sulla necessità di educazione: in primo luogo dei genitori «preoccupati e spesso angosciati per il futuro dei loro figli» degli insegnanti «che vivono la triste esperienza del degrado delle scuole» e della società stessa «che vede messe in dubbio dalla crisi dell’educazione le basi stesse della convivenza». Si evidenzia la necessità dell’educazione principalmente per le nuove generazioni. Ma la percezione d…

Patterning of Suitable Structures for the Investigation of the Josephson Effect in YBa2Cu3O7/PrBa2Cu3O7 Superlattices

1996

The aim of our work is to investigate the Josephson effect in YBa 2 Cu 3 O 7-δ /PrBa 2 Cu 3 O 7-δ superlattices. In the case of current flow along c axis direction the superlattice forms an array of artificial Josephson junctions where the YBa 2 Cu 3 O 7-δ layers are the superconducting electrodes which are separated but Josephson coupled by the PrBa 2 Cu 3 O 7-δ sheets. In this paper we report on the preparation, characterisation and patterning of the superlattices into suitable structures via standard photolithograpy and lift-off technique.

Josephson effect in superfluid atomic Fermi-gases

2002

We consider an analog of the internal Josephson effect in superfluid atomic Fermi-gases. Four different hyperfine states of the atoms are assumed to be trapped and to form two superfluids via the BCS-type pairing. Weshow that Josephson oscillations can be realized by coupling the superfluids with two laser fields. Choosing the laser detunings in a suitable way leads to an asymmetric below-gap tunneling effect for which there exists no analogue in the context of solid-state superconductivity.

From microscopic to macroscopic description of Josephson dynamics in one-dimensional arrays of weakly-coupled superconducting islands

2015

Abstract By starting from a microscopic quantum mechanical description of Josephson dynamics of a one-dimensional array of N coupled superconductors, we obtain a set of linear differential equations for the system order parameter and for additional macroscopic physical quantities. With opportune considerations, we adapt this description to two coupled superconductors, obtaining the celebrated Feynman model for Josephson junctions. These results confirm the correspondence between the microscopic picture and the semi-classical Ohta’s model adopted in describing the superconducting phase dynamics in multi-barrier Josephson junctions.

Lifetime of the superconductive state in short and long Josephson junctions

2008

We study the transient statistical properties of short and long Josephson junctions under the influence of thermal and correlated fluctuations. In particular, we investigate the lifetime of the superconductive metastable state finding the presence of noise induced phenomena. For short Josephson junctions we investigate the lifetime as a function both of the frequency of the current driving signal and the noise intensity and we find how these noise-induced effects are modified by the presence of a correlated noise source. For long Josephson junctions we integrate numerically the sine-Gordon equation calculating the lifetime as a function of the length of the junction both for inhomogeneous a…

Josephson junctions and superconducting field effect transistors based on epitaxial Bi2Sr2Can-1CunO2(n+2) thin films

1998

Abstract Josephson junctions based on thin films of the Bi2Sr2Ca2Cu3O10+δ compound show IcRn products compatible with YBa2Cu3O7−δ samples. Using quasiparticle tunneling experiments we found evidence for a superconductor–insulator–superconductor tunneling process via localized states in the barrier. The Bi2Sr2CaCu2O8+δ compound is investigated regarding possible applications in superconducting field effect devices. We present thin films of four unit cells thickness that are superconducting at 58 K. An inverted metal–insulator–superconductor structure was prepared. From the modulation of the normal state resistance we estimate a carrier density of 7×1019 cm−3 for a superconducting sample. The…

La stereotomia nella cattedra di Architettura statica di Carlo Giachery

2014

La scuola di architettura di Palermo, sin dalla sua fondazione nel 1779, con la creazione della cattedra di Architettura civile affidata a Giuseppe Venanzio Marvuglia, era divenuta inevitabilmente il luogo di verifica e talvolta di esplorazione dei temi legati alla pratica professionale e, quindi, all’arte del costruire. Giachery, Professore di Architettura statica e civile dal 1837 al 1865, è il primo ad avvertire, da docente, la crisi profonda del sistema didattico della scuola di architettura di Palermo isterilita dalla ricerca di astratte idealità neoclassiche e straniatasi dal processo evolutivo della cultura architettonica europea dopo la morte dei “maestri” Marviglia e Gentile. Secon…

The School of Architecture of Palermo since its founding in 1779 with the creation of the chair of Civil Architecture entrusted to Joseph Venantius Marvuglia has become the place of testing exploration of issues related to professional practice and the art of building. Carlo Giachery Professor of Static and Civil Architecture from 1837 to 1865 is the first to feel the deep crisis of the educational system of the school of architecture of Palermo. For him architecture and applied sciences to architecture found in their stereotomy confirmation of the existence of correspondent relationships in their evolutionary process. The notion of stereotomy taken by Carlo Giachery in teaching reconnects directly to the noble art of coupe des pierres. Taken together the teaching aids used to show a theoretical advance that Giachery inclined in the direction of elasticity of the materials. Noting the outcomes of teaching his students have the clear perception of how the teaching on stereotomy is the compendium of all the French tradition on the subject. With the establishment of the School of Application for Engineers and Architects in 1866 the steretomia seems to gradually lose interest in favor of the prevailing metal construction. All the wisdom of build which for centuries had been linked with art de la coupe des pierres gave way to new construction techniques and new materials.Settore ICAR/14 - Composizione Architettonica E Urbana

L'ecomuseo del grano e del pane: un percorso progettuale centrato sul design

2018

La festa di S. Giuseppe, oltre che un’importante e sentita ricorrenza religiosa, è a Salemi soprattutto la “festa dei pani”; bellissime realizzazioni di alto artigianato artistico, la cui sapienza si tramanda nelle famiglie e nelle associazioni di donne che per mesi lavorano alla produzione dell’enorme quantità delle piccole e grandi forme di pane, per rivestire le costruzioni votive che accolgono il rito della cena. Nasce quindi l’idea di proporre un “Ecomuseo del grano e del pane” nel Collegio dei Gesuiti, valorizzando e riaprendo al pubblico uno spazio di grande interesse storico-architettonico. Nell’ambito della consolidata collaborazione del Comune di Salemi con il Dipartimento di Arch…

The feast of St. Joseph as well as an important and heartfelt religious celebration is in Salemi above all the "feast of the loaves"beautiful achievements of high artistic craftsmanship whose wisdom is handed down in the families and in the associations of women who for many months work to produce the enormous quantity of small and large forms of bread to cover the votive constructions that welcome the ritual of dinner.Thus the idea of proposing an "Ecomuseum of wheat and bread" in the Jesuit College was born enhancing and re-opening a space of great historical-architectural interest to the public. As part of the consolidated collaboration of the Municipality of Salemi with the Department of Architecture professors and students worked on a strategic design project for museum set-up and communication also open forms of participation and sharing with the various territorial actors in a sort of 'social conversation' with the protagonists and skills in the field. A collaboration with Polimi Desis_Lab of the Milan Polytechnic concerning the contribution of the 'design of services for social innovation' was also initiated on these aspects.Settore ICAR/13 - Disegno Industriale

Noisy dynamics in long and short Josephson junctions

The study of nonlinear dynamics in long Josephson junctions and the features of a particular kind of junction realized using a graphene layer, are the main topics of this research work. The superconducting state of a Josephson junction is a metastable state, and the switching to the resistive state is directly related to characteristic macroscopic quantities, such as the current the voltage across the junction, and the magnetic field through it. Noise sources can affect the mean lifetime of this superconducting metastable state, so that noise induced effects on the transient dynamics of these systems should be taken into account. The long Josephson junctions are investigated in the sine-Gor…
