Effect of symmetry breaking on level curvature distributions
M. S. Hussein, C. P. Malta, M. P. Pato +1
We derive an exact general formalism that expresses the eigenvector and the eigenvalue dynamics as a set of coupled equations of motion in terms of the matrix elements dynamics. Co…

Distribution of matrix elements of random operators
M. S. Hussein, M. P. Pato
It is shown that an operator can be defined in the abstract space of random matrices ensembles whose matrix elements statistical distribution simulates the behavior of the distribu…

On the Evidence for Postacceleration Effects in Breakup Reactions with Halo Nuclei
C. A. Bertulani, M. S. Hussein, M. P. Pato +1
We study the postacceleration of charged fragments in reactions with unstable nuclear beams. For elastic breakup processes we show that the postaceleration effect can be well under…
