We investigate by molecular-dynamics simulations, the fast mobility-the rattling amplitude of the particles temporarily trapped by the cage of the neighbors-in mildly supercooled states of dense molecular (linear trimers) and atomic (binary mixtures) liquids. The mixture particles interact by the Lennard-Jones potential. The non-bonded particles of the molecular system are coupled by the more general Mie potential with variable repulsive and attractive exponents in a range which is a… 
Cage effect in supercooled molecular liquids: Local anisotropies and collective solid-like response.
It is concluded that the cage rattling is largely affected by solid-like extended modes, in close resemblance with experimental findings on colloids.
Thermodynamic scaling of vibrational dynamics and relaxation.
An expression of the TS master curve of the structural relaxation with one adjustable parameter less than the available three-parameter alternatives is derived and fits well with the experimental TS master curves of thirty-four glassformers and, in particular, their slope at the glass transition, i.e., the isochoric fragility.
Anisotropy of the monomer random walk in a polymer melt: local-order and connectivity effects
The results strongly suggest that the sole consideration of the local order is not enough to understand the microscopic origin of the rattling amplitude of the trapped monomer in the cage of the neighbours.
Dynamical, structural and chemical heterogeneities in a binary metallic glass-forming liquid
A structural analysis of slow clusters based on Voronoi tessellation evidences an increase with respect of the bulk system of the fraction of Cu atoms having a local icosahedral order in the dynamic slowing-down in supercooled metal alloys.
Dynamics of glass-forming liquids: Will theory and experiment ever meet?
The overall theme of this work has been to experimentally test the shoving model and isomorph theory related to the dynamics of glass-forming liquids, both of which, rather than being universal
Short-Time Elasticity of Polymer Melts: Tobolsky Conjecture and Heterogeneous Local Stiffness
An extended Molecular-Dynamics study of the short-time "glassy" elasticity exhibited by a polymer melt of linear fully-flexible chains above the glass transition is presented. The focus is on the
Thermodynamic scaling of relaxation: insights from anharmonic elasticity
This work proposes a method for evaluating both the characteristic exponent and the TS master curve that uses experimentally accessible quantities that characterise the anharmonic elasticity and does not use details about the microscopic interactions.
Elucidation of the Nature of Structural Relaxation in Glassy D-Sorbitol.
A novel approach is applied for exploring nontrivial interactions between structural units in d-sorbitol, a canonical example of a hydrogen-bonded organic glass, by introducing a dihedral-rearrangement indicator analysis to shed light on relaxation processes and dynamical heterogeneity.
The kinetic fragility of liquids as manifestation of the elastic softening
We show that the fragility m , the steepness of the viscosity and relaxation time close to the vitrification, increases with the degree of elastic softening, i.e. the decrease of the elastic modulus
Universal nature of dynamic heterogeneity in glass-forming liquids: A comparative study of metallic and polymeric glass-forming liquids.
An examination of particles having a locally preferred atomic packing, and clusters of such particles, suggests that there is no one-to-one relation between these populations of particles so that an understanding of the origin of DH in terms of static fluid structure remains elusive.


Scaling between structural relaxation and particle caging in a model colloidal gel
In glassy dynamics, the rattling of particles in a cage formed by their neighbors is typically limited to a length scale of the order of the particle diameter but is nevertheless strongly coupled to

It is found that the growth of domains formed by interconnected locally preferred structures signals the onset of the slow-dynamics regime and allows the rationalization of the different dynamic behaviors of the models.
Spatial displacement correlations in polymeric systems.
It is shown that states with identical average vibrational monomer displacement exhibit identical spatial correlations of the monomer displacements pertaining to the subsets of the fast and the slow monomers characterizing both the short-time and the long-time dynamical heterogeneities.
Non-Gaussian effects in the cage dynamics of polymers
The correlation between the fast cage dynamics and structural relaxation is investigated in a model polymer system. It is shown that the cage vibration amplitude, as expressed by the Debye–Waller
Scaling between relaxation, transport, and caged dynamics in polymers: from cage restructuring to diffusion.
The analysis carried out in terms of the van Hove function shows that the scaling does not depend on the specific quantity used to quantify both the relaxation times and the amplitude of the rattling motion, thus extending analogous results already known for atomic liquids.
Static and dynamic density effects due to the finite length of polymer chains: a molecular-dynamics investigation
The finite length of polymer chains affects both the static and the relaxation properties of the density of the melt state. These have been investigated by molecular-dynamics simulations of a
Scaling between relaxation, transport and caged dynamics in a binary mixture on a per-component basis.
The present study shows that the scaling does not need information concerning the arbitrarily-defined glass transition region and relies on a single characteristic length scale a(2)(1/2) which is determined even far from that region and provides a link between the fast dynamics and the thermodynamic scaling of the slow dynamics.
Competition of the connectivity with the local and the global order in polymer melts and crystals.
The competition between the connectivity and the local or global order in model fully flexible chain molecules is investigated by molecular-dynamics simulations and reveals that increasing the number of shell bonds decreases the FCS order in both melt and crystal.
Dynamics of entangled linear polymer melts: A molecular‐dynamics simulation
We present an extensive molecular‐dynamics simulation for a bead spring model of a melt of linear polymers. The number of monomers N covers the range from N=5 to N=400. Since the entanglement length
Free volume properties of a linear soft polymer: a computer simulation study.
Molecular dynamics simulation of a linear soft polymer has been performed and the free volume properties of the system have been analyzed in detail in terms of the Voronoi polyhedra of the monomers.
