First clear evidence of quantum chaos in the bound states of an atomic nucleus
L. Muñoz, R. A. Molina, J. M. G. Gómez +1
We study the spectral fluctuations of the Pb nucleus using the complete experimental spectrum of 151 states up to excitation energies of MeV recently identified at t…

Noise in Spectral Fluctuations of Quantum Systems
J. M. G. Gomez, A. Relano, J. Retamosa +4
The power law in the power spectrum characterizes the fluctuating observables of many complex natural systems. Considering the energy levels of a quantum system as a discre…

Stringent Numerical Test of the Poisson Distribution for Finite Quantum Integrable Hamiltonians
A. Relano, J. Dukelsky, J. M. G. Gomez +1
Using a new class of exactly solvable models based on the pairing interaction, we show that it is possible to construct integrable Hamiltonians with a Wigner distribution of neares…
