I do not believe that there are any.

You can check Stephanie Singer's book on Lie groups as applied as symmetries of differential equations, and also the book on mechanics and look at the unfortunately old-fashioned review
http://people.ucsc.edu/~rmont/papers/Symm_in_Mech_Review.PDF

There you will see that although there is some research activity, it is what a physicist would consider "pure math", e.g., the possibility of collisions in the three body problem. And this activity, also in Symplectic Geometry and Lorentzian manifolds, takes place in the mathematics community, it is not done or interesting to physicists. And Prof. Singer herself is now doing Statistics...just like me: she left Lie Groups to do Stats, as I did too.

Statistical Mechanics is the future of Physics.

Now Lie Groups do play an important role in Statistical Mechanics, see Mackey's wonderful review article in the Bulletin of the American Mathematical Society, and Volume 4 of Gelfand and Naimark's Les Distributions: applications de l'analyse harmonique (I am sure there is an English translation, too). And some of that activity is indeed Physics, although what is grouped around Ergodic Theory and particularly interested Mackey was purely mathematical.
