Oral presentation

The advent of time-domain and multimessenger astronomy opens new perspectives to study the most energetic phenomena of our universe, and identify the mysterious sources of ultra-high-energy cosmic rays and high-energy neutrinos. In my thesis, I developed new analytical and numerical tools to study the production of cosmic rays, gamma rays and neutrinos from various populations of energetic...

Oral presentation

Magnetic skyrmions are nanoscale non-collinear configurations of the magnetic order, featuring specific topological properties. This talk will present how the proper balance of several magnetic interactions allows for their stabilization up to room temperature. One key ingredient is the presence of a Dzyaloshinskii-Moriya antisymmetric exchange interaction, which will be discussed from an...
