Title:Supersolids: the theoretical point of view.
Seminar:Department of Mathematics Colloquium
Speaker:Yves Pomeau, ENS-Paris
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.
