Chaos and quantization of the three-particle generic Fermi-Pasta-Ulam-Tsingou model II: phenomenology of quantum eigenstates
Hua Yan, Marko Robnik
We undertake a thorough investigation into the phenomenology of quantum eigenstates, in the three-particle FPUT model. Employing different Husimi functions, our study focuses on bo…

Chaos and quantization of the three-particle generic Fermi-Pasta-Ulam-Tsingou model I: Density of states and spectral statistics
Hua Yan, Marko Robnik
We study the mixed-type classical dynamics of the three-particle Fermi-Pasta-Ulam-Tsingou (FPUT) model in relationship with its quantum counterpart, and present new results on aspe…
