| Abstract: |

| There are very strong indications that solid Helium at very low
temperature becomes very special in the sense that its momentum of inertia
is less than what could be derived from the bulk rotation of this
material. This property of Non classical rotational inertia (NCRI) was
predicted by Leggett long ago as a consequence of the basic principles of
quantum mechanics, but it remains somewhat controversial. I shall explain
that NCRI can be proved to exist in a fully explicit mathematical model.
This model is not fully realistic for solid Helium. Nevertheless, by
borrowing some of the ideas derived from it, one can obtain accurate and
quantitative estimates of NCRI as well as predict new physical effects. |
