Aging in the retrieval phase of the Hopfield model

Montemurro, Marcelo A. and Tamarit, Francisco A. (2001). Aging in the retrieval phase of the Hopfield model. Physica A: Statistical Mechanics and its Applications, 295(1-2) pp. 108–113.



In this work we present a numerical study of the complex dynamical behavior of the Hopfield model within its retrieval phase. We find that the spin glass solutions that coexist with the retrieval attractors display a rich out of equilibrium dynamics suggesting the presence of a very intricate phase space structure, which resembles that of the Sherrington–Kirkpatrick model.
