Glass glass transition and new dynamical singularity points in an analytically solvable p-spin glass like model

摘要

We introduce and analytically study a generalized p-spin glass like modelthat captures some of the main features of attractive glasses, recently foundby Mode Coupling investigations, such as a glass/glass transition line anddynamical singularity points characterized by a logarithmic time dependence ofthe relaxation. The model also displays features not predicted by the ModeCoupling scenario that could further describe the attractive glasses behavior,such as aging effects with new dynamical singularity points ruled bylogarithmic laws or the presence of a glass spinodal line.
