Entanglement dynamics of two independent qubits in environments with and without memory
No full textHere is analyzed the dynamics of two-qubit entanglement, when the two qubits are initially in a mixed extended Werner-like state and each of them is in a zero temperature non-Markovian environment. The dependence of entanglement dynamics on the purity and degree of entanglement of the initial states and on the amount of non-Markovianity is also given. This extends the previous work about non-Markovian effects on the two-qubit entanglement dynamics for initial Bell-like states [Bellomo et al., Phys. Rev. Lett. 99, 160502 (2007)]. The effect on the two-qubit entanglement dynamics of nonzero temperature in Markovian environments is finally studied

complesso (ovvero all'interno di un sistema complesso, o ancora tra
individui le cui interazioni sono complesse). Il modello si basa su un
opportuno sviluppo dei metodi della teoria cinetica matematica per
particelle “attive”, con particolare riguardo al modellamento delle
interazioni multiple. Si propone un primo approccio all'analisi della
complessità, con riferimento sia agli aspetti computazionali che a
quelli inerenti il modello “formale

No full textL’Italia settentrionale e le guerre civili del 68-69 d.C.
No full textLe guerre civili del 68‐69 segnarono uno spartiacque nella storia dell’impero romano. Sebbene generate da movimenti di ribellione scaturiti in alcune delle province più importanti dell’impero, esse conobbero il loro epilogo finale in Italia settentrionale, e in particolar modo presso la comunità di Bedriacum, dove furono combattute le due battaglie decisive. Il presente lavoro si prefigge di analizzare che impatto ebbero questi scontri sulle comunità locali e in che modo queste ultime parteciparono attivamente (o passivamente) alle fasi più acute della lunga guerra civile. In particolare, vengono ripercorse le vicende del consolare di origine milanese L. Verginio Rufo, che rifiutò in ben due occasioni la porpora imperiale, dei soldati di origine transpadana che militarono negli eserciti impegnati nella regione, e della città di Cremona, che proprio a causa della sua discussa lealtà venne distrutta a termine di questo longus et unus annus.The civil wars of the years 68‐69 represented a watershed in the history of the Roman empire. Even though they originated in some key provinces, they knew their final stage in Northern Italy, and especially near the site of Bedriacum, where the two most important battles of the war were fought. This study aims to analyse the impact of these conflicts on the local communities of Northern Italy, and the latter’s participation in the most crucial phases of the fights. Particularly, it fol‐ lows the actions of L. Verginius Rufus, a man of consular rank who came from Milan and that twice refused an imperial acclamation, of the soldiers of North‐ Italian origins that fought in this area, and of Cremona, a town that due to its disputed loyalty was destroyed at the very end of the war

No full textAfter the announcement of the armistice between Italy and the Allies the Royal Italian Army, forced to an unequal showdown with the German forces, was put in a dire situation. In spite of its inferiority, however, many Italian units bravely, and in many places successfully, resisted to the Wehrmacht’s assault founding one of the cornerstones of the later «Resistenza» movement. In this article the author, after a brief summary of the happenings which led to the armistice, focuses the attention on the fighting occurred in the city of Bari where an assaulting German elite unit was forced to surrender by an hete-rogeneous Italian force recollected and led by the general Nicola Bellomo. In the last part of the work the author deals with the faultiness of the memory about these events in the subsequent historiography and, in particular, he re-examines from an innovative point of view the events which led to the incri-mination and condemnation of the general Bellomo by a british Military Court at the end of the war
