Vibrational echoes: Dephasing, rephasing, and the stability of classical trajectories
Article Abstract:
The proposition that the classical mechanical nonlinear response function for a thermal ensemble of anharmonic oscillators diverges in time is presented along with arguments favoring it. It has been found that, within the domain of classical mechanics, infrared pulse sequences can provide a sensitive probe of the stabilities of classical trajectories, even for a system in thermodynamic equilibrium.

Spontaneous relaxation in generalized oscillator models with glassy dynamics
Article Abstract:
The generalized oscillator model (GOM) referred as a new family of exactly solvable models is introduced by zero-temperature relaxation determined by entropy barriers and partial equilibration, to investigate theoretical aspects related to the statistical description of the aging state. It is reported that, GOMs offer a conceptual framework to develop a statistical description of the aging state.
