Seminario sul Compton scattering inverso

Il 15 novembre alle ore 14,30 presso la sala riunione 412, Luca Serafini (Istituto Nazionale di Fisica Nucleare) terra' un seminario dal titolo

Can an electron emit a photon of energy larger than its own?¶

Abstract

The newly discovered effect of Full Inverse Compton Scattering has shown several implications to unexpected phenomena, like the achievement of extremely high accelerations with electrons coming to a sudden stop from relativistic velocities, therefore showing potentialities of detecting Unruh radiation, and opening a portal towards quantum gravity, and like the emission of photons with energy larger than that of the emitting electron, in apparent violation of energy conservation.
We will discuss these new findings with an eye at the historical development, throughout the last century, in the understanding of QED electron-photon interactions, from the nuclear bomb development to the first studies on cosmic rays, to the development of modern Inverse Compton Scattering advanced sources of X/gamma rays. Full Inverse Compton Scattering can have significant impacts also in other fields like plasma physics, with the capability of trapping electrons (positrons) in magnetic bottles, with the spectral purification of broadband gamma ray photon beams, and with several possibile implications in the field of gamma ray cosmic sources.
