Aging Dynamics of the Heisenberg Spin Glass
L. Berthier, A. P. Young
We numerically study the non-equilibrium dynamics of the three dimensional Heisenberg Edwards-Anderson spin glass following a sudden quench to its low temperature phase. The subseq…
Time and length scales in spin glasses
Ludovic Berthier, A. P. Young
We discuss the slow, nonequilibrium, dynamics of spin glasses in their glassy phase. We briefly review the present theoretical understanding of the spectacular phenomena observed i…
Time and length scales in supercooled liquids
Ludovic Berthier
We numerically obtain the first quantitative demonstration that development of spatial correlations of mobility as temperature is lowered is responsible for the ``decoupling'' of t…
Dynamic criticality in glass-forming liquids
Stephen Whitelam, Ludovic Berthier, Juan P. Garrahan
We propose that the dynamics of supercooled liquids and the formation of glasses can be understood from the existence of a zero temperature dynamical critical point. To support our…
Real space origin of temperature crossovers in supercooled liquids
Ludovic Berthier, Juan P. Garrahan
We show that the various crossovers between dynamical regimes observed in experiments and simulations of supercooled liquids can be explained in simple terms from the existence and…
Energetics of clusters in the two-dimensional Ising spin glass
Ludovic Berthier, A. P. Young
We study numerically the properties of local low-energy excitations in the two-dimensional Ising spin glass. Given the ground state, we determine the lowest-lying connected cluster…
A consequence of local equilibration and heterogeneity in glassy materials
Ludovic Berthier
The existence of a generalized fluctuation-dissipation theorem observed in simulations and experiments performed in various glassy materials is related to the concepts of local equ…
Finite size scaling analysis of the glass transition
Ludovic Berthier
We show that finite size scaling techniques can be employed to study the glass transition. Our results follow from the postulate of a diverging correlation length at the glass tran…
Non-topographic description of inherent structure dynamics in glass formers
Ludovic Berthier, Juan P. Garrahan
We show that the dynamics between inherent structures in glass forming systems can be understood in purely dynamical terms, without any reference to ``topographic'' features of the…
Fluctuation-dissipation relations in the non-equilibrium critical dynamics of Ising models
Peter Mayer, Ludovic Berthier, Juan P. Garrahan +1
We investigate the relation between two-time, multi-spin, correlation and response functions in the non-equilibrium critical dynamics of Ising models in d=1 and d=2 spatial dimensi…
