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.
