Constant of motion identifying excited-state quantum phases
Ángel L. Corps, Armando Relaño
We propose that a broad class of excited-state quantum phase transitions (ESQPTs) gives rise to two different excited-state quantum phases. These phases are identified by means of…

Distribution of the Ratio of Consecutive Level Spacings for Different Symmetries and Degrees of Chaos
A. L. Corps, A. Relaño
Theoretical expressions for the distribution of the ratio of consecutive level spacings for quantum systems with transiting dynamics remain unknown. We propose a family of one-para…

Stringent Test on Power Spectrum of Quantum Integrable and Chaotic Systems
A. L. Corps, A. Relaño
Quantum chaotic and integrable systems are known to exhibit a characteristic and noise, respectively, in the power spectrum associated to their spectral fluctuation…
