Potere e legittimità nel mondo carolingio. Un'analisi comparativa a partire dai casi di Grifone, Bernardo d'Italia e Pipino II d'Aquitania.

This dissertation examines the evolution of narrative constructions of legitimacy in the Carolingian world through a comparative analysis of the strategies of delegitimisation displayed in various sources. The starting point of this thesis, in fact, is that one assertive and functional means for a ruler to improve his own legitimacy was to undermine another’s. In the Carolingian era, we witness the monopolisation of historical narrative by the literary circles of the courts of Pippin III, Cha...

X-ray induced temperature dependent amorphous-amorphous transitions in the GeO2 glass

Glasses are non-equilibrium materials whose structure and dynamics can be strongly modified by external perturbations such as ionizing radiation. This thesis investigates the effects of intense X-ray irradiation on vitreous germanium dioxide (v-GeO₂), a prototypical strong oxide glass, by combining X-ray photon correlation spectroscopy (XPCS), X-ray diffraction (XRD), and inelastic X-ray scattering (IXS). The results demonstrate that intense X-rays induce atomic dynamics and structural transf...

Dihedral non-Abelian Lattice Gauge Theories: Physics and Quantum Simulation

Lattice gauge theories provide a first-principles, non-perturbative formulation of the fundamental interactions of the Standard Model, and their Hamiltonian reformulation on a quantum simulator offers a promising route to regimes---real-time dynamics, finite baryon density---that lie beyond the reach of Euclidean Monte Carlo methods. With the ultimate goal of overcoming these shortcomings, over the last decade, quantum simulations of Abelian lattice gauge theories have expanded from the first...

Combined Machine Learning Analysis for Antihelium Search with the AMS-02 Experiment

Heavy anti-nuclei, such as antihelium, are unlikely to be formed during cosmic rays (CRs) propagation, as supported by measurements from the PHENIX and ALICE collaborations. The precise measurement of cosmic-ray antinuclei is a powerful probe for possible identification of Dark Matter (DM) signatures, and in combination with measurements of other cosmic-ray species, can help constrain cosmic-ray production and propagation in the Galaxy. The first-time discovery of cosmic-ray antihelium has be...

From Climate Education to Sustainability Education: Physics Education Across Diverse Educational Contexts

This thesis investigates how science education, and particularly physics education, can contribute to sustainability education across different educational contexts, using with climate change as the main entry point. More specifically, the work explores how the understanding of climate-related physical phenomena can support broader educational approaches capable of engaging social, cultural, political, emotional, and epistemological dimensions of sustainability. The work began from the analys...

Deciphering tranSNPs: functional genetic variants shaping protein output and cancer-related phenotypes

This study investigates the impact of genetic diversity, in the form of single-nucleotide polymorphisms (SNPs), on the post-transcriptional control of gene expression, to identify a novel class of functional SNPs, named tranSNPs, with potential applications as biomarkers for cancer diagnosis, prognosis, or targeted therapy; tranSNPs are defined as SNPs whose allelic fraction is significantly imbalanced across polysome-bound and total mRNAs. We provide a comprehensive characterization of tranS...

Beyond qubits: Quantum optimization and lattice gauge theories in a qudit framework

Quantum computing holds the promise of tackling problems that are intractable for classical machines, yet the path from current noisy intermediate-scale quantum (NISQ) devices to fault-tolerant processors demands both better algorithms and a deeper understanding of how to exploit the full structure of quantum hardware. A key direction in this effort is the move beyond qubits: exploiting higher-dimensional local Hilbert spaces — qudits — to encode information, enforce constraints, and simulate...
