Time Quasi-periodic unbounded perturbations of Schrödinger operators and KAM methods

Dario Bambusi, Sandro Graffi

We eliminate by KAM methods the time dependence in a class of linear differential equations in subject to an unbounded, quasi-periodic forcing. This entails the pure-point…

Statistics of energy levels and zero temperature dynamics for deterministic spin models with glassy behaviour

M. Degli Esposti, C. Giardina', S. Graffi +1

We consider the zero-temperature dynamics for the infinite-range, non translation invariant one-dimensional spin model introduced by Marinari, Parisi and Ritort to generate glassy…

Absolute Continuity of the Floquet Spectrum for a Nonlinearly Forced Harmonic Oscillator

Sandro Graffi, Kenji Yajima

We prove that the Floquet spectrum of a class of time-periodic Schroedinger equations under a a mildly nonlinear resonant forcing is purely absolutely continuous.
