Exploring the Quantum/Classical Frontier - Recent Advances in Macroscopic Quantum Phenomena
Quantum mechanical laws are well documented at the level of a single or a few atoms and are here extended to systems containing 102 to 1010 electrons - still much smaller than the usual macroscopic objects, but behaving in a manner similar to a single atom. Besides the purely theoretical interest, such systems pose a challenge to the achievement of the ultimate microelectronic applications. The present volume presents an up-to-date account of the physics, technology and expected applications of quantum effects in solid-state mesoscopic structures. Physical phenomena include the Aharonov-Bohm effect, persistent currents, Coulomb blockade and Coulomb oscillations in single electron devices, Andreev reflections and the Josephson effect in superconductor/normal/superconductor systems, shot noise suppression in microcontacts and contact resistance quantisation, and overall quantum coherence in mesoscopic and nanoscopic structures related to the emerging physics of quantum computation in the solid-state environment.
The on-going developments, and the recent achievements of the superconducting electronics (especially in the field of Josephson junctions and the inherent nonlinear dynamics) inspired us to organize a conference where different groups working on the subject could meet and discuss the latest results of their investigations. This idea was realized as two joint workshops, the NATO Advanced Research Workshop on Superconducting Electronics with Prof. N.F. Pedersen as chairman, and the 2nd Workshop on Josephson Devices, with Profs. G. Costabile and M. Russo as chairmen, held in Capri, Italy on September 3-7, 1990. The Workshops were very successful. About 70 scientists from 12 countries (Denmark, ...
This volume gives the state-of-the-art on superconducting tunnel junctions as X-ray detectors for low energy radioastronomy. Contributions from major experts of the main laboratories in the world are included. They cover many aspects of the subject, from nonequilibrium phenomena in STJ to the detector design optimization, and report the most recent experimental results in the field.
Their mission was humble and simple: to reach the poor country people, who suffered from ignorance of their faith, a debased clergy, and poverty. In response, Vincent De Paul defined the vocation of his “Little Company” as preaching local missions for free, educating the clergy, and working to relieve the people’s poverty. Soon, however, this vocation was complicated by commands to minister to royal families, including Louis xiv of France and the kings and queens of Poland, which would embroil the Vincentians in international and ecclesiastical politics. In addition, they would begin dangerous foreign missions, such as ministering to the Christian captives of the Barbary pirates, the d...
[Italiano]: La storiografia degli ultimi decenni, sulla base dell’edizione di numerose fonti, ha provveduto a revisionare il tema della diffusione della riforma monastica nell’Italia Meridionale. A fronte del marginale influsso di movimenti più largamente affermatisi in Europa, si registra invece la nascita di una pluralità di esperienze alla ricerca di un modello autoctono di stampo eremitico e pastorale. Fra queste, a pieno titolo, va inscritta anche la congregazione di S. Maria del Gualdo. Attraverso l’analisi di un eterogeneo complesso di fonti superstiti questo lavoro si prefigge di ricostruire la genesi del carisma fondazionale e la storia della famiglia religiosa. Muovendo dal...
