Level statistics for one-dimensional Schr\"odinger operators and Gaussian beta ensemble

We study the level statistics for two classes of 1-dimensional random Schr"odinger operators : (1) for operators whose coupling constants decay as the system size becomes large, and (2) for operators with critically decaying random potential. As a byproduct of (2) with our previous result \cite{KN} imply the coincidence of the limits of circular and Gaussian beta ensembles.
