Goal of the 4DPHOTON project is the development and construction of a photon imaging detector with unprecedented performance. The proposed device will be capable of detecting fluxes of single-photons up to one billion photons per second, over areas of several square centimetres, and will measure - for each photon - position and time simultaneously with resolutions better than ten microns and few tens of picoseconds, respectively. These figures of merit will open many important applications allowing significant advances in particle physics, life sciences or other emerging fields where excellent timing and position resolutions are simultaneously required. Our goal will be achieved thanks to the use of an application-specific integrated circuit in 65 nm complementary metal-oxide-semiconductor (CMOS) technology, that will deliver a timing resolution of few tens of picoseconds at the pixel level, over few hundred thousand individually-active pixel channels, allowing very high rates of photons to be detected, and the corresponding information digitized and transferred to a processing unit. As a result of the 4DPHOTON project we will remove the constraints that many light imaging applications have due to the lack of precise single-photon information on four dimensions (4D): the three spatial coordinates and time simultaneously. In particular, we will prove the performance of this detector in the field of particle physics, performing the reconstruction of Cherenkov photon rings with a timing resolution of ten picoseconds. With its excellent granularity, timing resolution, rate capability and compactness, this detector will represent a new paradigm for the realisation of future Ring Imaging Cherenkov detectors, capable of achieving high efficiency particle identification in environments with very high particle multiplicities, exploiting time-association of the photon hits.

Interferometers are fundamental tools for the study of nature laws and for the precise measurement and control of the physical world. In the last century, the scientific and technological progress has proceeded in parallel with a constant improvement of interferometric performances. For this reason, the challenge of conceiving and realizing new generations of interferometers with broader ranges of operation and with higher sensitivities is always open and actual. Despite the introduction of laser devices has deeply improved the way of developing and performing interferometric measurements with light, the atomic matter wave analogous, i.e. the Bose-Einstein condensate (BEC), has not yet triggered any revolution in precision interferometry. However, thanks to recent improvements on the control of the quantum properties of ultra-cold atomic gases, and new original ideas on the creation and manipulation of quantum entangled particles, the field of atom interferometry is now mature to experience a big step forward. The system I want to realize is a Mach-Zehnder spatial interferometer operating with trapped BECs. Undesired decoherence sources will be suppressed by implementing BECs with tunable interactions in ultra-stable optical potentials. Entangled states will be used to improve the sensitivity of the sensor beyond the standard quantum limit to ideally reach the ultimate, Heisenberg, limit set by quantum mechanics. The resulting apparatus will show unprecedented spatial resolution and will overcome state-of-the-art interferometers with cold (non condensed) atomic gases. A successful completion of this project will lead to a new generation of interferometers for the immediate application to local inertial measurements with unprecedented resolution. In addition, we expect to develop experimental capabilities which might find application well beyond quantum interferometry and crucially contribute to the broader emerging field of quantum-enhanced technologies.

"Recent developments in image-making techniques have resulted in a drastic blurring of the threshold between the world of the image and the real world. Immersive and interactive virtual environments have enabled the production of pictures that elicit in the perceiver a strong feeling of being incorporated in a quasi-real world. In doing so such pictures conceal their mediateness (their being based on a material support), their referentiality (their pointing to an extra-iconic dimension), and their separateness (normally assured by framing devices), paradoxically challenging their status as images, as icons: they are veritable “an-icons”. This kind of pictures undermines the mainstream paradigm of Western image theories, shared by major models such as the doctrine of mimesis, the phenomenological account of image-consciousness, the analytic theories of depiction, the semiotic and iconological methods. These approaches miss the key counter-properties regarding an-icons as ""environmental"" images: their immediateness, unframedness, and presentness. Subjects relating to an-icons are no longer visual observers of images; they are experiencers living in a quasi-real environment that allows multisensory affordances and embodied agencies. AN-ICON aims to develop “an-iconology” as a new methodological approach able to address this challenging iconoscape. Such an approach needs to be articulated in a transdisciplinary and transmedial way: 1) HISTORY – a media-archaeological reconstruction will provide a taxonomy of the manifold an-iconic strategies (e.g. illusionistic painting, pre-cinematic dispositifs, 3D films, video games, head mounted displays); 2) THEORY – an experiential account (drawing on phenomenology, visual culture and media studies) will identify the an-iconic key concepts; 3) PRACTICES – a socio-cultural section will explore the multifaceted impact of an-iconic images, environments and technologies on contemporary professional domains as well as on everyday life.

Dante Alighieri at the dawn of the 1300s, as well as Eustache Deschamps almost a century later, conceived poetry as music in itself. But what happens with poetry when it is involved in the complex architecture of polyphony? The aim of this project is to study for the first time the corpus of 14th- and early 15th-century poetry set to music by Ars Nova polyphonists (more than 1200 texts). This repertoire gathers different poetic and musical traditions, as shown by the multilingual anthologies copied during the last years of the Schism. The choice of this corpus is motivated by two primary goals: a) to offer a new interpretation of its meaning and function in the cultural and historical context, one that may be then applied to the rest of coeval European lyric poetry; b) to overcome current disciplinary divisions in order to generate a new methodological balance between the project’s two main fields of interest (Comparative Literature / Musicology). Most Ars Nova polyphonists were directly associated with religious institutions. In many texts, the language of courtly love expresses the values of caritas, the theological virtue that guides wise rulers and leads them to desire the common good. Thus, the poetic figure of the lover becomes a metaphor for the political man, and love poetry can be used as a device for diplomacy, as well as for personal and institutional propaganda. From this unprecedented point of view, the project will develop three research lines in response to the following questions: 1) How is the relationship between poetry and music, and how is the dialogue between the different poetic and musical traditions viewed in relation to each context of production? 2) To what extent does Ars Nova poetry take part in the ‘soft power’ strategies exercised by the entire European political class of the time? 3) Is there a connection between the multilingualism of the manuscript tradition and the perception of the Ars Nova as a European, intercultural repertoire?
