摘要：

The parametric sensitivity of complex quantum systems is characterized by the distribution of eigenvalue curvatures k, defined as the second derivative of the eigenvalues with respect to a perturbation parameter. For systems without time-reversal symmetry (unitary ensemble), the exact distribution is found to be P(k) = (2/pi)[1 + k2]-2. This proves a recent conjecture by Zakrzewski and Delande [Phys. Rev. E 47, 1650 (1993)].
