Dr. Torre was employed in ENEA in 1987, and she is now senior researcher in the UTAPRAD-MAT Laboratory at the ENEA Research Center of Frascati (Rome).
After presenting in 1983 the thesis (intitled Cavità ottica per un laser ad elettroni liberi (LELA): sensibilità al disallineamento ed ottimizzazione del guadagno) at the University of Naples on the characterization of optical cavities for the Free Electron Laser (FEL) under implementation at the INFN-National Laboratory of Frascati, Dr. Torre started an intense collaboration with the FEL research team at the Frascati ENEA Center.
Specifically, she was involved in the investigation of the FEL dynamics from the quantum viewpoint, approached within the context of the Lie-algebra based formalism. Then, the similarity of the quantum dynamics of the FEL to that of a two-level system interacting with an e.m. field naturally suggested the application of the same Lie-algebra based techniques to the latter as well as to other related topics.
Accordingly, the Lie algebra method has been effectively applied to the evolution of two and three level quantum systems of quite general forms, thus addressing the general issue of the solution of evolutionary differential equations.
The two books, G. Dattoli, A. Renieri and A. Torre, Lectures on Free Electron Laser Theory and related topics, (World. Sci. Publ. Co., Singapore 1993) and F. Ciocci, G. Dattoli, A. Torre and A. Renieri, Insertion Devices for Synchrotron Radiation and Free Electron Laser, (World. Sci. Publ. Co., Singapore 2000), can be considered as a synthesis of the research activity concerned with the FEL dynamics.
On the other hand, stimulated by the calculation of quantities related to the FEL statistical properties, that are expressible by series involving special functions, the interest in special functions gained its own place within Dr. Torre’s research work. In particular, the extended analysis of the generalized Bessel functions had as a result the publication of the specifically devoted book G. Dattoli and A. Torre, Theory and Applications of Generalized Bessel Functions (Aracne Ed., Roma 1996).
Eventually all of her expertise has migrated into classical optics, finding its natural location into the optical phase space representation, based on the Wigner distribution function formalism. This research activity concretized into the publication of the book A. Torre, Linear ray and Wave Optics in Phase Space (Elsevier, Amsterdam, 2005).
Later Dr Torre was involved in the Italian research project concerning the Extreme Ultra-Violet Lithography (FIRB project Prototipo per nanofabbricazione di chip per elettronica e di dispositivi di optoelettronica basato su microlitografia EUV), which led to the realization of a laboratory-scale system offering high-resolution patterning. In particular, her research activity in this context was concerned with the issue of Schwarzschild objective design optimization and plasma-emitted debris characterization and mitigation, the latter being central to the European project for EUVL More Moore. For such a work, the ENEA research team involved in the FIRB project received the ENEA Excellence Award for the MET-EGERIA EUVL apparatus in 2008, and a special mention for the related oral contribution at the XCIV National Congress of the Italian Society of Physics (Genoa, 22-27 September 2008).
The present activity of Dr. Torre regards specifically optical propagation problems, approached through the paraxial wave equation.
She is a reviewer for Mathematical Reviews, Optics Express, Optics Letters, Journal of the Optical Society of America A, Journal of Optics, Optics Communications, Journal of Optics and Laser Technology, Optics and Lasers in Engineering, PIER&JEMWA, Applied Physics B, Journal of Physics A, Le Matematiche and Journal of Mathematics. Finally, she is listed among the evaluators for the Romanian National Research Council (CNCS).
