Talk 1: Nuclear Fission and the Liquid Drop Model

Abstract: The critical mass in nuclear fission is predicted by the liquid drop model. This talk is devoted to a mathematical treatment of the corresponding variational problem. In particular, I will discuss joint results with Rupert Frank on the existence and non-existence of minimizers.

Talk 2: The Ionization Conjecture in the Thomas–Fermi–Dirac–von Weizs?cker Theory

Abstract: We will discuss a proof of the ionization conjecture in the TFDW theory, obtained by combining techniques developed for the liquid drop model with Solovej’s renormalization method for the Thomas–Fermi theory. This is joint work with Rupert Frank and Hanne Van Den Bosch.
