La paratragedia in Aristofane: ricerche sulla ricezione del tragico nel V sec. a.C.
Full text linkTra i tratti caratteristici della commedia antica merita attenzione la paratragedia, ovvero la ripresa in ambito comico di passi tragici, con o senza intento parodico dell’autore. Partendo dal saggio Paratragodia di Peter Rau, ancora fondamentale su questo argomento, il lavoro di ricerca intende innanzitutto elaborare una nuova catalogazione del materiale tragico presente nelle commedie di Aristofane, concentrandosi sui drammi di Eschilo, Sofocle ed Euripide giuntici frammentariamente, e alla luce di quanto emerso riflettere, laddove possibile, se alla base delle citazioni e allusioni tragiche si possa individuare la visione della messa in scena teatrale oppure la fruizione libraria
Engineering multiphoton states for linear optics computation
No full textTransformations achievable by linear optical components
allow to generate the whole unitary group only when restricted to the one-photon subspace of a multimode Fock space. In this paper, we address the more general problem of encoding quantum information by multiphoton states, and elaborating it via ancillary extensions, linear optical passive devices and photodetection. Our scheme stems
in a natural way from the mathematical structures underlying the physics of linear optical passive devices. In particular, we analyze an economical procedure for mapping a fiducial 2-photon 2-mode state into an arbitrary 2-photon 2-mode state using ancillary resources and linear optical passive N-ports assisted by post-selection. We found that adding a single ancilla mode is enough to generate any
desired target state. The effect of imperfect photodetection in post-selection is considered and a simple trade-off between success probability and fidelity is derived

Exploring Representation Theory of Unitary Groups via Linear Optical Passive Devices
No full textIn this paper, we investigate some mathematical structures underlying the physics of linear optical passive (LOP) devices. We show, in particular, that with the class of LOP
transformations on N optical modes one can associate a unitary representation of U(N) in the N-mode Fock space, representation which can be decomposed into irreducible sub-representations living in the subspaces characterized by a fixed number of photons. These (sub-)representations
can be classified using the theory of representations of semi-simple Lie algebras. The remarkable case where N = 3 is studied in detail
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
