Breit-Wigner to Gaussian transition in strength functions
V. K. B. Kota, R. Sahu
Employing hamiltonians defined by two-body embedded Gaussian orthogonal ensemble of random matrices(EGOE(2)) plus a mean-field producing one-body part, strength functions (for stat…

Nature of matrix elements in the quantum chaotic domain of interacting particle systems
V. K. B. Kota, R. Sahu
There is a newly emerging understanding that in the chaotic domain of isolated finite interacting many particle systems smoothed densities define the statistical description of the…

Transition Strength Sums and Quantum Chaos in Shell Model States
V. K. B. Kota, R. Sahu, K. Kar +2
For the embedded Gaussian orthogonal ensemble (EGOE) of random matrices, the strength sums generated by a transition operator acting on an eigenstate vary with the excitation energ…
