Informācija par kolokviju (angļu valodā):
One of the most fundamental processes of light-matter interaction is the scattering of photons by atoms and ions. Three main channels contribute to this process, namely scattering by bound electrons, a nucleus and quantum fluctuations of the vacuum. In his presentation, Andrey Surzhykov will review recent experimental and theoretical investigations of these scattering channels. In particular, he will show how the analysis of soft x-ray scattering by bound electrons can be used as an effective tool to determine the lifetimes of highly charged ions. Regarding the high energy regime, we will discuss how an accurate treatment of the interaction of electron-positron pairs with the Coulomb field of a nucleus has resolved the long-standing discrepancy between experimental and theoretical findings for the Delbrück scattering. Moreover, the significance of elastic photon scattering as a key process for the Gamma Factory initiative at CERN will be highlighted.
