The new space mission NeUtrino and Seismic Electromagnetic Signals (NUSES) will investigate low-energy and ultra high energy cosmic rays, the Sun-Earth environment, space weather, and the magnetosphere-ionosphere-lithosphere connection (MILC). Through its two payloads, Zirè and Terzina, NUSES will be a trailblazer for the development and testing of innovative technologies (such as cutting-edge...
In recent years, High-Temperature Superconductors (HTS) have gained prominence in high-field applications, not only due to their elevated critical temperature (Tc) but also owing to their superior critical magnetic field (Bc2) at lower temperatures, surpassing 100 T and outperforming conventional superconductors in this regard. Recent advancements in practical conductor development based on...
Quantum phenomena are currently at the forefront of scientific inquiry, offering insights into exotic electronic phases within matter. My research focuses on unlocking the mysteries of these phases in atomically thin Van der Waals materials. Through an innovative electrostatic doping technique called space charge doping, we have developed a method that safeguards the sample's surface while...
In 1998, observations of distant stellar explosions provided striking evidence that the expansion of the Universe is accelerating. The cosmology community has struggled to find an explanation for this phenomenon ever since, postulating the existence of a mysterious form of “dark energy” driving the expansion. However, the lack of theoretical understanding of its properties motivates the search...
T2K is a long-baseline neutrino experiment based in Japan. Its Near Detector complex is undergoing a significant update; in particular, part of the ND280 detector is being replaced by three new subdetectors: SFGD, two HA-TPCs, a TOF.
The latter was completely designed, assembled, tested and commissioned by the DPNC of UniGe. The commissioning is still ongoing and has included several...
Over recent years, the detection of organic compounds has arisen as a cornerstone for security, health, environmental and pollution issues. The ability to measure low concentrations of gases such as methane, methanol, or nitrogenous compounds, allows to perform tasks such as practical medical diagnoses, explosives detection, or the prevention of pollution from various sources, including...
FASER, an experiment at the LHC, was designed to explore the existence of light, weakly interacting particles that are generated in proton-proton collisions at the ATLAS interaction point and travel in the far-forward direction. The initial data analysis focused on two searches: the decay of dark photons into an electron-positron pair and the charged-current interaction of muon neutrinos...
Imaging Atmospheric Cherenkov Telescopes (IACTs) play a crucial role in probing the high-energy universe through the detection of very-high-energy gamma rays. The accuracy and reliability of these instruments are contingent upon precise calibration methodologies. Examining the ring-shaped images generated by muons within IACTs offers a robust and accurate approach for calibrating the...
The exceptionally accurate Standard Model (SM) theory of fundamental interactions is known to be incomplete. Many new theories extend the SM, trying to solve some of the most compelling puzzles of nature, such as the Dark Matter (DM) enigma. Some simplified models predict the existence of bosons mediating interactions between SM and DM particles. These new force mediators could appear as...
The principle of emergence leads to new insights on the measurement problem and the Higgs mechanism, by showing their relation to magnetism and superconductivity, respectively.
In this talk, we will review what peculiar velocities are and how they can help us in better understanding both our local universe and its cosmological components. In particular, we will focus on the information we can extropolate from the Pantheon+SH0es and CosmicFlow4 datasets
The Cherenkov Telescope Array (CTA), conceived as an array of tens of imaging atmospheric Cherenkov telescopes (IACTs), is an international project for a next-generation ground-based gamma-ray observatory. CTA aims to improve on the sensitivity of current-generation instruments a factor of five to ten and will provide energy coverage from 20 GeV to more than 300 TeV. Arrays of IACTs probe the...
Transition metal dichalcogenides like molybdenum disulfide (MoS$_2$) have been studied on metal surfaces, but little is known about twist angle-dependent electronic properties of these simple heterostructures, which indeed offers tremendous opportunities to design functional quantum materials. In this talk, I will present a detailed scanning tunneling microscopy and spectroscopy investigation...
Abstract
Preclinical studies often overlook lung mucus barriers, crucial for drug permeation. This research uses a patient-derived 3D cell culture model to examine lanthanide-doped upconverting nanoparticles (UCNPs) with different surface coatings. Tracking UCNPs via upconverting emissions reveals significant differences in mucus residence time and mucociliary clearance. Positively charged,...
The climate is a nonlinear dynamical system driven by the inhomogeneous energy received from the Sun. The redistribution of energy involves a multitude of processes acting at various spatial and temporal scales. These processes are interconnected, leading to the existence of a multitude of feedback loops that can amplify or compensate each other.
A steady state is reached when a balance...
(Poster) Cosmological observations are well described by the LCDM model, a universe with a cold dark matter component and a cosmological constant acting as dark energy. However, more and more cosmological tensions have emerged in the past decades, putting this simple model into question. A large amount of research has focused on the quest for an alternative model of modified gravity and dark...
The T2K[1] collaboration is upgrading the near detector (ND280) with four additional subdetectors: a time of flight detector (TOF), two high-angle TPCs (HATPC), and the super fine grained detector (Super-FGD).
The Super-FGD consists of 2 million scintillator cubes read by optic fibers along three directions, allowing three-dimensional track reconstruction in a 2-tons fiducial mass...
The highly energetic nature of gamma rays renders their terrestrial observation impossible, as they interact with the atmosphere, producing particle showers. These particles then become a source of Cherenkov radiation, subsequently detected by an array of ground-based telescopes. Their cameras record images which are then parametrized. The parameters are fed to random forests to reconstruct...
Proton beam therapy can potentially offer improved treatment for cancers of the head and neck and in paediatric patients. Proton therapy is a promising new type of cancer treatment, can be targeted more directly at the tumor and does less damage to other tissue. Treatments are currently planned using conventional X-ray CT images. It is happening due to the absence of devises able to perform...
Bulk orthorhombic T$_d$-MoTe$_2$ is a type-II Weyl semimetal and becomes superconducting at a critical temperature of $T_c = 0.1\,\text{K}$. Remarkably, superconductivity becomes far more robust in the 2D limit, contrary to generic models and the established trend in ultrathin metal films. Recent transport measurements reported a gradual increase in $T_c$ as the thickness is reduced with $T_c$...
The Alpha Magnetic Spectrometer-02 (AMS-02) experiment is a magnetic spectrometer on the International Space Station (ISS) that can measure the flux of particles from cosmic sources in a rigidity window ranging from GVs to a few TVs and up to at least Nickel (charge Z=28). Measuring Mn, Fe, Cl, and Ar fluxes with high precision can constrain models of cosmic ray propagation. The challenge is...
