Spectral Statistics of the Triaxial Rigid Rotator: Semiclassical Origin of their Pathological Behavior
V. R. Manfredi, V. Penna, L. Salasnich
In this paper we investigate the local and global spectral properties of the triaxial rigid rotator. We demonstrate that, for a fixed value of the total angular momentum, the energ…
Pathological Behavior in the Spectral Statistics of the Asymmetric Rotor Model
V. R. Manfredi, L. Salasnich
The aim of this work is to study the spectral statistics of the asymmetric rotor model (triaxial rigid rotator). The asymmetric top is classically integrable and, according to the…
Anomalous Spectral Statistics of the Asymmetric Rotor Model
V. R. Manfredi, L. Salasnich
We investigate the spectral statistics of the asymmetric rotor model (triaxial rigid rotator). The asymmetric top is classically integrable and, according to the Berry-Tabor theory…
Energy Level Quasi-Crossings: Accidental Degeneracies or Signature of Quantum Chaos?
V. R. Manfredi, L. Salasnich
In the field of quantum chaos, the study of energy levels plays an important role. The aim of this review paper is to critically discuss some of the main contributions regarding th…
Different Facets of Chaos in Quantum Mechanics
V. R. Manfredi, L. Salasnich
Nowadays there is no universally accepted definition of quantum chaos. In this paper we review and critically discuss different approaches to the subject, such as Quantum Chaology…
Mean--Field and Nonlinear Dynamics in Many--Body Quantum Systems
V. R. Manfredi, L. Salasnich
In this paper we discuss in detail the nonlinear equations of the mean--field approximation and their connection to the exact many--body Schrödinger equation. Then we analyze the m…
