Star-product approach to quantum field theory: The free scalar field
1990
The star-quantization of the free scalar field is developed by introducing an integral representation of the normal star-product. A formal connection between the Feynman path integral in the holomorphic representation and the star-exponential is established for the interacting scalar fields.
Coronal Loops: Observations and Modeling of Confined Plasma
2010
Coronal loops are the building blocks of the X-ray bright solar corona. They owe their brightness to the dense confined plasma, and this review focuses on loops mostly as structures confining plasma. After a brief historical overview, the review is divided into two separate but not independent sections: the first illustrates the observational framework, the second reviews the theoretical knowledge. Quiescent loops and their confined plasma are considered, and therefore topics such as loop oscillations and flaring loops (except for non-solar ones which provide information on stellar loops) are not specifically addressed here. The observational section discusses loop classification and popula…
Nuove Ricerche a Castellazzo di Poggioreale. Campagne 2008-2009.
2012
Resoconto preliminare di due campagne di scavo nel sito indigeno di Monte Castellazzo, Valle del Belice, Sicilia. Viene descritto un muraglione con scalinata di età medievale costruito lungo il costone 540. Sono anche descritte le varie fasi di vita di una capanna protostorica di VIII-VII secolo a.C. e di un edificio a pianta rettangolare di età arcaica fine VII-VI sec. a.C. Sono infine illustrati gli interessantissimi reperti di un deposito di fondazione, comprendenti ceramica "elima" e greca di importazione, pesi da telaio, metalli allo stato grezzo e altri fittili di notevole qualità.
Laboratory disruption of scaled astrophysical outflows by a misaligned magnetic field
2021
The shaping of astrophysical outflows into bright, dense, and collimated jets due to magnetic pressure is here investigated using laboratory experiments. Here we look at the impact on jet collimation of a misalignment between the outflow, as it stems from the source, and the magnetic field. For small misalignments, a magnetic nozzle forms and redirects the outflow in a collimated jet. For growing misalignments, this nozzle becomes increasingly asymmetric, disrupting jet formation. Our results thus suggest outflow/magnetic field misalignment to be a plausible key process regulating jet collimation in a variety of objects from our Sun’s outflows to extragalatic jets. Furthermore, they provide…
