An inequality for Fourier transform
It seems to me that the inequality follows from Plancherel inequality and the identity $\widehat{(\Delta)^{\alpha}f}=x^{2\alpha}\widehat{f}$.

Better bound for HardyLittlewood maximal function
Testing your estimate on the characteristic of a ball, you see that when $\alpha\rightarrow+\infty$ you get a contradiction.

Elliptic Harnack inequality for 1D Schrodinger operator?
A Harnack inequality with constants depending on the radius may be found in Aizenman, M.; Simon, B. Brownian motion and Harnack inequality for Schrödinger operators.

Heat Equation on $[0,T] \times \mathbb{R}^n$
Duhamel formula could be the tool to prove such a result, by a contraction mapping argument. wiki.math.toronto.edu/DispersiveWiki/index.php/…

Converse to Chow's theorem in subriemannian geometry
Thank you very much! Unfortunately there are many "linguistic" differences between Control Theory texts and Subriemannian Geometry ones that may make not very appropriate to quote Jurdjevic book while discussing subriemannian geometry. Do you know of any "subriemannian" reference for the result I look for? Thank you very much!

Uncertainty principle on finite groups
You may know this, but Theorem 2 in arxiv.org/pdf/math/0608702v2.pdf shows that the kind of uncertainty principle you quoted holds for compact (in particular finite) groups, appropriately reworded.

What is Kirillov's method good for?
I think the paper linked above by Peter Dalakov was incorporated (and expanded) in Kirillov's book Lectures on the Orbit Method, which you may already know.
