Glassy systems are characterized by an extremely sluggish dynamics without any simple sign of long range order. It is a debated question whether a correct description of such phenomenon requires the emergence of a large correlation length. We prove rigorous bounds between length and time scales implying the growth of a properly defined length when the relaxation time increases. Our results are valid in a rather general setting, which covers finite-dimensional and mean field systems.As an…

Order in glassy systems
A directly measurable correlation length may be defined for systems having a two-step relaxation, based on the geometric properties of a density profile that remains after averaging out the fast
Evidence for a spinodal limit of amorphous excitations in glassy systems
What is the origin of the sharp slowdown displayed by glassy systems? Physical common sense suggests there must be a concomitant growing correlation length, but finding this length has been
A simple one dimensional glassy Kac model
We define a new family of random spin models with one-dimensional structure, finite-range multispin interactions, and bounded average degree (number of interactions in which each spin participates).
Assessing the role of static length scales behind glassy dynamics in polydisperse hard disks
It is shown that a glass former, polydisperse hard disks, has a strong increase of structural order, well correlated with slow dynamics, which goes undetected by the pinning method, casting a serious doubt on the order-agnostic nature of the PTS length and its relevance to slow dynamics.
Theory of high-dimensional liquids and glasses
The dynamics of liquids, regarded as strongly-interacting classical particle systems, remains a field where theoretical descriptions are limited. So far, there is no microscopic theory starting from
Linking dynamical heterogeneity to static amorphous order
Glass-forming liquids grow dramatically sluggish upon cooling. This slowdown has long been thought to be accompanied by a growing correlation length. Characteristic dynamical and static length
Can the glass transition be explained without a growing static length scale?
This work suggests that the efficiency of SWAP stems from a postponed onset of glassy dynamics, and describes this effect in terms of "crumbling metastability" and uses the example of nucleation to illustrate the possibility of circumventing free-energy barriers of thermodynamic origin by a change in the local dynamical rules.
Theory of fluctuations in disordered systems
In this thesis we have studied many aspects of the physics of disordered and glassy systems. The first part of the work is about the theory of dynamical fluctuations in the beta regime. When a system
Quantitative field theory of the glass transition
By studying the soft modes that appear at the dynamical temperature, an effective theory for the critical fluctuations is obtained and a Ginzburg criterion is obtained that states the range of validity of the analysis.
Theory of Simple Glasses: Exact Solutions in Infinite Dimensions
This pedagogical and self-contained text describes the modern mean field theory of simple structural glasses. The book begins with a thorough explanation of infinite-dimensional models in statistical


Out of equilibrium dynamics in spin-glasses and other glassy systems
We review recent theoretical progress on glassy dynamics, with special emphasis on the importance and universality of the ``aging regime'', which is relevant to many experimental situations. The
On the Dynamics of the Glass Transition on Bethe Lattices
The Glauber dynamics of disordered spin models with multi-spin interactions on sparse random graphs (Bethe lattices) is investigated. Such models undergo a dynamical glass transition upon decreasing
Direct Experimental Evidence of a Growing Length Scale Accompanying the Glass Transition
New multipoint dynamical susceptibilities are introduced to estimate quantitatively the size of these regions and provide direct experimental evidence that the glass formation of molecular liquids and colloidal suspensions is accompanied by growing dynamic correlation length scales.
From Large Scale Rearrangements to Mode Coupling Phenomenology in Model Glasses
We consider the equilibrium dynamics of Ising spin models with multi-spin interactions on sparse random graphs (Bethe lattices). Such models undergo a mean field glass transition upon increasing the
Diverging length scale and upper critical dimension in the Mode-Coupling Theory of the glass transition
We show that the glass transition predicted by the Mode-Coupling Theory (MCT) is a critical phenomenon with a diverging length and time scale associated to the cooperativity of the dynamics. We
Growing range of correlated motion in a polymer melt on cooling towards the glass transition
Many liquids cooled to low temperatures form glasses (amorphous solids) instead of crystals. As the glass transition is approached, molecules become localized and relaxation times increase by many
Recipes for metastable states in spin glasses
In this paper we develop further a metl~od recently introduced by one of us to study metastable states in spm glasses. We consider a 'potential function', defined as the free energy of a system at a
The mean-field infinite range p = 3 spin glass: Equilibrium landscape and correlation time scales
We investigate numerically the dynamical behavior of the mean field 3-spin spin glass model: we study equilibrium dynamics, and compute equilibrium time scales as a function of the system size V. We
Growing Spatial Correlations of Particle Displacements in a Simulated Liquid on Cooling toward the Glass Transition
We define a correlation function that quantifies the spatial correlation of single-particle displacements in liquids and amorphous materials. We show that for an equilibrium liquid this function is
