Earth rotation turns event timing into a geometric probe of UHE neutrino origin
Andrew Cheek, João Paulo Pinheiro, Jordi Salvado
It has been proposed that the ultra-high-energy (UHE) event detected by KM3NeT could be explained by dark matter (DM) decay. Prima facie this seems unlikely becau…
Seafloor Topography Enhances KM3NeT Sensitivity to ANITA-like Events
Carlos A. Argüelles, Toni Bertólez-Martínez, Alba Burgos-Mondéjar +3
In this article, we introduce the concept of topographic enhancement in the context of ultra-high-energy neutrino detection by underwater neutrino telescopes. We demonstrate that t…
BBN bounds on neutrinophilic ultralight Dark Matter
Toni Bertólez-Martínez, Justo López-Sarrión, Jordi Salvado
The high densities in the early Universe provide a unique laboratory to constrain couplings between feebly interacting particles, such as dark matter and neutrinos. In this article…
Characterization of quantum entanglement via a hypercube of Segre embeddings
Joana Cirici, Jordi Salvadó, Josep Taron
A particularly simple description of separability of quantum states arises naturally in the setting of complex algebraic geometry, via the Segre embedding. This is a map describing…
