Seminario del Departamento de Física Teórica: “From the graviton to gravity”.- Jueves 2 de noviembre
El jueves 2 de noviembre de 2023 a las 12:10 h José M. Gracia Bondía (DFTUZ) impartirá el seminario de título “From the graviton to gravity”. La charla tendrá lugar en el Seminario de Física Teórica, Edificio de Físicas.
Resumen:
We try to lift a corner of the veil covering "dequantization", in the realm of gravitational theory. As it happens, quantum gravitational interactions involve more complication that just the coupling of stress-energy-momentum tensor to gravitons. A rigorous approach based on the autonomous formulation of QFT demands graviton's self-interaction, leading to the (perturbative development of) Einstein's action.
