Abstract :
Vector soliton formation is expected in the case at which light dark photons account for the dark matter content in the Universe. If such spin-1 particles couple to electromagnetism
via dimension-6 operators, vector solitons, under right conditions, would undergo instability via parametric resonance. The outgoing radiation would bring imprints from the rich dark photon soliton structure and dark photon-photon coupling nature, opening a window for future detection.
Biography:
Professor Enrico D. Schiappacasse obtained with the highest honor his bachelor degree in astronomy at Pontifical Catholic University of Chile (2011), Santiago, Chile. After that, he moved to Massachusetts, USA, to pursue doctoral studies in physics as Fulbrighter fellow, U.S. Department of State. He received his PhD. in physics at Tufts University in 2018, being formed by Mark P. Hertzberg (worldwide expert in axion physics) and Lawrence H. Ford (recognized expert on quantum gravity). After his PhD., Prof. Schiappacasse spent a few years as postdoctoral researcher at the Institute of Nuclear and Particle Physics, Shanghai Jiao Tong University, China, and at the cosmological groups of the University of Jyväskylä and University of Helsinki, Finland. During this time, he led several innovative projects related to indirect searches of dark matter candidates (axions, WIMPs and primordial black holes) in various well-motivated cosmological scenarios. In 2022, he moved to Rice University, Texas, USA, as postdoctoral associate and Rice Academy Junior Fellow, to lead projects regarding the formation, evolution, and associated astrophysical signatures of compact objects composed of high spin boson dark matter. In 2024, Prof. Schiappacasse joined at the senior level the faculty of San Sebastian University, Santiago, Chile. Professor Schiappacasse is an expert in Bose-Einstein condensate of axions, holding several highly cited papers which have significantly improved our axion physics understanding. His research interests rest in the interfase between cosmology, astrophysics and particle physics.
