Lower bound on the four-point dynamical susceptibility: Direct experimental test on a granular packing
F. Lechenault, O. Dauchot, G. Biroli +1
We track the motion of a horizontally vibrated amorphous assembly of bidisperse hard disks, for densities ranging across the jamming transition. We derive on very general grounds a…
Statistical mechanics of a single particle in a multiscale random potential: Parisi landscapes in finite dimensional Euclidean spaces
Yan V Fyodorov, Jean-Philippe Bouchaud
We construct a N-dimensional Gaussian landscape with multiscale, translation invariant, logarithmic correlations and investigate the statistical mechanics of a single particle in t…
The Student ensemble of correlation matrices: eigenvalue spectrum and Kullback-Leibler entropy
Giulio Biroli, Jean-Philippe Bouchaud, Marc Potters
We study a new ensemble of random correlation matrices related to multivariate Student (or more generally elliptic) random variables. We establish the exact density of states of em…
Quantum plasticity and dislocation-induced supersolidity
Jean-Philippe Bouchaud, Giulio Biroli
We suggest that below a certain temperature T_k, the free energy for the creation of kinks-antikinks pairs in the dislocation network of solid He4 becomes negative. The underlying…
On an explicit construction of Parisi landscapes in finite dimensional Euclidean spaces
Yan V. Fyodorov, Jean-Philippe Bouchaud
We construct a N-dimensional Gaussian landscape with multiscale, translation invariant, logarithmic correlations and investigate the statistical mechanics of a single particle in t…
Spatial correlations in the dynamics of glassforming liquids: Experimental determination of their temperature dependence
Cécile Dalle-Ferrier, Caroline Thibierge, Christiane Alba-Simionesco +6
We use recently introduced three-point dynamic susceptibilities to obtain an experimental determination of the temperature evolution of the number of molecules, N_corr, that are dy…
