Abstract
The low temperature Monte Carlo dynamics of an ensemble of linear harm onic oscillators shows some entropic barriers related to the difficult y of finding the directions in configurational space which decrease th e energy. This mechanism is enough to observe some typical non-equilib rium features of glassy systems like activated-type behavior and aging in the correlation function and in the response function. Due to the absence of interactions the model only displays a one-step relaxation process. (C) 1998 Elsevier Science B.V. All rights reserved.
