Topological order in Josephson junction ladders with Mobius boundary conditions

We propose a CFT description for a closed one-dimensional fully frustrated ladder of quantum Josephson junctions with Mobius boundary conditions, in particular we show how such a system can develop topological order. Such a property is crucial for its implementation as a "protected" solid state qubit.Comment: 14 pages, 3 figures, to appear in JSTA

Augustin Bea auf dem Weg zum Ökumeniker 1949-1960

Focusing on the correspondence between Augustin Bea SJ, who was Holy Office’s consultant and Pacelli’s confessor, and Lorenz Jaeger, bishop of Paderborn and referent for the ecumenical questi- ons at the Bishops’ Conference of Fulda, this study provides a reconstruction of the „ecumenical conversion“ which lead the first one to act as a link between Rome and the circles of Catholic ecumenism, above all the German ones, during the pontificate of Pius XII. It was Jaeger, indeed, who chose Bea, among the many consultors of the Holy Office, as a contact men for ecumenical questions to be submitted to the Holy See, putting him at the crossroads of a network of contacts and relationships which involved also the ecumenical circles in Switzerland, Austria and Holland. The correspondence between the two men takes place since 1951 and its reconstruction permits to study the evolution of the ecumenical thought of the Jesuit and his attitude towards the question of individual conversions, the activities of the movement Una Sancta and the evolution of the World Council of Churches

Environmental sustainability approaches and positive energy districts: A literature review

During the last decade, increasing attention has been paid to the emerging concept of Positive Energy Districts (PED) with the aim of pushing the transition to clean energy, but further research efforts are needed to identify design approaches optimized from the point of view of sustainable development. In this context, this literature review is placed, with a specific focus on environmental sustainability within innovative and eco-sustainable districts. The findings show that some sustainability aspects such as sustainable food, urban heat islands mitigation and co-impacts, e.g., green gentrification, are not adequately assessed, while fragmented thinking limits the potential of circularity. In this regard, targeted strategies should be developed. On the other hand, the Key Performance Indicators framework needs some integrations. In this direction, indicators were suggested, among those defined in the Sustainable Development Agenda, the main European standards and initiatives and the relevant literature experiences. Future outlooks should be directed to-wards: the harmonization of the Life Cycle Assessment in PEDs with reference to modeling assump-tions and analysis of multiple impacts; the development of dynamic environmental analyses taking into account the long-term uncertainty due to climate change, data availability and energy decar-bonization; the combination of Life Cycle Assessment and Key Performance Indicators based tech-niques, from a holistic thinking perspective, for a comprehensive design environment and the analysis of the contribution of energy flexibility approaches on the environmental impact of a project

Gli archivi dell’Azione cattolica italiana

L'articolo illustra i fondi presenti nell'archivio dell’Istituto per la storia dell’Azione cattolica e del movimento cattolico in Italia “Paolo VI”. Nato con il compito di conservare, raccogliere, ordinare e rendere disponibile per la ricerca storica tutto il materiale documentario relativo all’Azione cattolica italiana, nonché ad enti e personalità collegate ad essa o al movimento cattolico più in generale, l’archivio costituisce di fatto una preziosa risorsa testimoniale per ricostruire la storia del panorama cattolico italiano da una prospettiva per larga parte inedita, non coincidente con le posizioni ufficiali di curia ed episcopato, né con la storia politica della democrazia cristiana. Tra i fondi disponibili, anche le carte private di protagonisti del cattolicesimo italiano, come Luigi Gedda e Carlo Carrett
