Numerical Study of Aging in the Generalized Random Energy Model
Munetaka Sasaki, Koji Nemoto
Magnetizations are introduced to the Generalized Random Energy Model (GREM) and numerical simulations on ac susceptibility is made for direct comparison with experiments in glassy…
Analysis on Aging in the Generalized Random Energy Model
Munetaka Sasaki, Koji Nemoto
A new dynamics more natural than that proposed by Bouchaud and Dean is introduced to the Generalized Random Energy Model, and the master equation for the dynamics is solved exactly…
Memory Effect, Rejuvenation and Chaos Effect in the Multi-layer Random Energy Model
Munetaka Sasaki, Koji Nemoto
We introduce magnetization to the Multi-layer Random Energy Model which has a hierarchical structure, and perform Monte Carlo simulation to observe the behavior of ac-susceptibilit…
Scaling Law and Aging Phenomena in the Random Energy Model
Munetaka Sasaki, Koji Nemoto
We study the effect of temperature shift on aging phenomena in the Random Energy Model (REM). From calculation on the correlation function and simulation on the Zero-Field-Cooled m…
