The production of neutron beams with optimal energy and angular distributions is crucial for Boron Neutron Capture Therapy (BNCT). While the 7Li(p,n) reaction is well established, the 9Be(p,xn) reaction is characterized by scarce data and inaccurate descriptions. We developed a model for the beryllium reaction that incorporates two dominant channels: (p,n), supported by experimental data, and...

Quantum computing is often presented as a route to solving classically intractable problems, yet this promise is fundamentally constrained by limited hardware resources. This poster explores how this tension can be addressed across quantum simulation, quantum chemistry, and quantum machine learning.
In quantum simulation, key challenges lie in the efficient preparation of physically...

Given Dirac fields on AdS$_n$ in Poincaré chart, one wishes to classify the boundary conditions at conformal infinity that ensure the existence of advanced and retarded propagators. Here this analysis is carried out for each mass window. In particular, the well-known MIT-bag class is distinguished from a generalized family, thereby extending to arbitrary dimensions the procedure initiated...

Silicon nitride (Si₃N₄) is a widely used platform for integrated nonlinear and quantum photonics, yet its amorphous nature prevents access to second-order processes such as second-harmonic generation (SHG) and spontaneous parametric down-conversion (SPDC). We show that an all-optical poling mechanism can permanently inscribe a photo-induced χ(2) response within SiN microresonators, breaking...

We report on the non-volatile control of the electronic ground state of octahedral TiSe$_{2}$ by means of electric field-driven hydrogen intercalation via ionic liquid gating. Based on measurements of electrical transport, dc magnetometry, and muon-spin rotation, we demonstrate that charge-density wave and superconductivity coexist in H$_{x}$TiSe$_{2}$ through most of the electronic phase...

A number of numerical approaches has been developed to study quantum field theories in non-perturbative regimes. One method consists in confining space-time to a finite volume and discretizing it, allowing for ab initio simulations. In the case of Quantum Chromodynamics (QCD), this framework is known as Lattice QCD. Another strategy is to numerically diagonalize the Hamiltonian of the theory,...

Among the currently open questions in particle physics are the origin of the extremely small neutrino masses, and the nature of dark matter. One possibility to solve both problems is to consider neutrinos as Majorana particles, and extend the Standard Model with three additional particles, the heavy neutral leptons (HNLs). In this model, the masses of these particle species are related, such...

The European Strategy for Particle Physics identified an electron-positron Higgs factory as the highest priority next collider. From a calorimetry point of view, precision measurements at these accelerators require excellent hadronic energy resolution ($\sim \frac{30\%}{\sqrt{E}}$), especially in multi-jet events, to successfully separate Z, W, and Higgs decays.\
