If you have a question about this talk, please contact Dr G Moller.

In the first part of the talk I introduce the physics of superconducting nanograins: theories, experiments, their limitations and why we are still far from a good understanding of this problem. Then I will persuade the audience that there are reasons to be optimistic about the future of this field: recent developments make possible for the first time an accurate comparison between theory and experiments. This is paving the way to exploit quantum size effects in boosting superconductivity in nanograins. Finally I investigate the conditions under which finite size effects can enhance substantially the critical temperature of iron-based superconductors.

This talk is part of the Theory of Condensed Matter series.
