Seminario del Departamento de Física Teórica: “Schwinger process on the surface of hot quark star”.- Lunes 23 de junio
El lunes 23 de junio de 2025 a las 12:00 h se celebrará un nuevo Seminario del Departamento de Física Teórica impartido por Mikalai Prakapenia (ICRANet-Minsk, B.I. Stepanov Institute of Physics, National Academy of Sciences of Belarus, 220072 Nezalezhnasci Av. 68-2, Minsk, Belarus), con el título “Schwinger process on the surface of hot quark star”. Tendrá lugar en el Seminario de Física Teórica, ubicado en la primera planta del Edificio A (Físicas).
Resumen (en inglés):
Supercritical electric fields, in which the Schwinger effect is possible, can exist in a thin surface layer of compact astrophysical objects,such as hypothetical quark stars and neutron stars. For completely degenerate stellar configurations, the Pauli exclusion principle does not allow the Schwinger effect to be realized, but for hot stars the situation is different. The report will show that a hot quark star is a source of electron-positron pairs, and the energy release in the pairs can be comparable to the energy release in the neutrino channel.
