Muñoz, Laura ; Fernández Ramírez, César ; Relaño Pérez, Armando ; Retamosa Granado, Joaquín | Elsevier Science BV | 2012-03-29We present a robust analysis of the spectral fluctuations exhibited by the light meson spectrum. This analysis provides information about the degree of chaos in light mesons and may be useful to get some insight on the underlying interactions. O[...]texto impreso
Relaño Pérez, Armando ; Dukelsky, J. ; Gómez Gómez, José María ; Retamosa Granado, Joaquín | American Physical Society | 2004-08Using a 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 nearest-neighbor level spacings. However, these Hamiltonians involve many-b[...]texto impreso
Relaño Pérez, Armando ; Faleiro, E. ; Gómez Gómez, José María ; Molina, R. A. ; Muñoz, L. ; Retamosa Granado, Joaquín | American Physical Society | 2004-12-10It was recently conjectured that 1/ƒ noise is a fundamental characteristic of spectral fluctuations in chaotic quantum systems. This conjecture is based on the power spectrum behavior of the excitation energy fluctuations, which is different for[...]texto impreso
Kota, V. K. B. ; Relaño Pérez, Armando ; Retamosa Granado, Joaquín ; Vyas, Manan | IOP Publishing | 2008-10-01Using the ergodicity principle for the expectation values of several types of observables, we investigate the thermalization process in isolated fermionic systems. These are described by the two-body random ensemble, which is a paradigmatic mode[...]
