QUANTUM LEVEL STATISTICS USEFUL FOR MESOSCOPIC PHYSICS

We report on two results from our computational studies in quantum lev el statistics as a contribution to mesoscopic physics: (i) parametric motion of complex quantum levels and its dynamic treatment of second-d erivative distribution for neighboring pairs (the so-called curvature distribution); (ii) intermediate statistics for long-range level corre lation which exhibits a fractional power law, i.e., another manifestat ion of the fractional-power dependence like S-beta (0 < beta < 1) fami liar to Brody's distribution, in the number variance and the Delta-sta tistics of Dyson-Mehta.
