Simulating critical anion chemistry with indirect excitons.

The maximal ionization problem is a basic open question in quantum chemistry: given a nucleus of charge Z, what is the maximal number of electrons that this nucleus can bind? Based on observations, it is conjectured that this number equals Z+C, where C is a universal constant independent of Z, most likely equal to unity. Nobody has succeeded in proving such a bound to date and only partial results in this direction exist. Some theoretical work has also been performed on a slightly reformulated version of this problem, that is, given N electrons, what is the minimal value of the nuclear charge Z, treated as a continuous parameter, that is able to bind them? It is known, for instance, that this Z is about 0.91e for N=2. In this talk, we are going to discuss a possible experimental platform for the study of this basic yet surprisingly difficult question. Joint work with K. Jachymski.
