Excited-state phase transition leading to symmetry-breaking steady states in the Dicke model
Ricardo Puebla, Armando Relaño, Joaquín Retamosa
We study the phase diagram of the Dicke model in terms of the excitation energy and the radiation-matter coupling constant . Below a certain critical value of the coupling…
Spectral-statistics properties of the experimental and theoretical light meson spectra
L. Munoz, C. Fernandez-Ramirez, A. Relano +1
We 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 ma…
Thermalization in the Two-Body Random Ensemble
V. K. B. Kota, A. Relaño, J. Retamosa +1
Using the ergodicity principle for the expectation values of several types of observables, we investigate the thermalization process in isolated fermionic systems. These are descri…
1/f noise in experimental Sinai quantum billiards
E. Faleiro, U. Kuhl, R. A. Molina +3
It was recently conjectured that 1/f noise is a fundamental characteristic of spectral fluctuations in chaotic quantum systems. In this Letter we show that the level fluctuations o…
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…
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…
