1/f noise in the Two-Body Random Ensemble
A. Relano, R. A. Molina, J. Retamosa
We show that the spectral fluctuations of the Two-Body Random Ensemble (TBRE) exhibit 1/f noise. This result supports a recent conjecture stating that chaotic quantum systems are c…

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…
