In this paper, we study the superconvergence phenomenon in the free central
limit theorem for identically distributed, unbounded summands. We prove not
only the uniform convergence of the densities to the semicircular density but
also their Lp-convergence to the same limit for p>1/2. Moreover, an
entropic central limit theorem is obtained as a consequence of the above
results.Comment: Published in at http://dx.doi.org/10.1214/09-AOP505 the Annals of
