Atoms with bosonic `electrons' have always been more of a theoretical fancy than a model of real physical matter, at best suited to illustrate how important the Pauli principle is in our world, but mainly of only academic interest to mathematical physicists. All this is about to change in the not-too-distant future if the recently discovered anti-alpha particles (anti-He nuclei which are twice positively charged bosons in their nuclear ground state) can be produced in sufficiently large numbers, captured, and substituted for the conventional electrons in the atomic hull around conventional nuclei (a similar feat has already been accomplished with anti-protons, but these are fermions, not bosons). In my talk I will try to survey what is mathematically rigorously known about atoms with bosonic `electrons' and, more importantly, present a list of interesting open problems which still await their solution.
