Melting is analyzed dynamically as a problem of localization at a liquid-solid interface. A Lindemann-like criterion of melting is derived in terms of particular vibrational amplitudes, which turn out to equal a universal quotient (about one-tenth) of the molecular spacing, at the interface. The near universality of the Lindemann ratio apparently arises owing to strongly overdamped dynamics near melting, and despite the anharmonic interactions being system-specific. A similar criterion is…

Liquid state elasticity and the onset of activated transport in glass formers.
The crossover temperature to activated transport in glass-forming liquids can be predicted using their finite-frequency elastic constants and the fusion entropy using the notion that, at the crossover, the "Lindemann ratio" of this vibrational displacement to the corresponding lattice spacing is nearly system-independent.
Universality of the onset of activated transport in Lennard-Jones liquids with tunable coordination: implications for the effects of pressure and directional bonding on the crossover to activated transport, configurational entropy, and fragility of glassforming liquids.
It is established that the crossover to activated transport in liquids takes place when the depth of the metastable minimum in the free energy corresponding to long-lived aperiodic structures reaches a certain near universal value, and the particle vibrational displacement is strongly correlated with this depth in a broad range of pressure and temperature.
Microscopic calculation of the free energy cost for activated transport in glass-forming liquids.
This work independently shows how to estimate this surface tension and, hence, the activation barrier for the activated transport for several actual liquids, using their structure factors and knowledge of the finite-frequency elastic constants.
Theory of the structural glass transition: a pedagogical review
The random first-order transition theory of the structural glass transition is reviewed in a pedagogical fashion. The rigidity that emerges in crystals and glassy liquids is of the same fundamental
On the mechanism of activated transport in glassy liquids.
It is confirmed that the entropic droplet picture is indeed not only internally consistent but is also fully constructive, consistent with the apparent success of its many quantitative predictions.
Charge and momentum transfer in supercooled melts: why should their relaxation times differ?
The methodology allows one to single out other contributions to the conductivity, as in "superionic" liquids or when charge carriers are delocalized, implying that in those systems, charge transfer does not require structural reconfiguration.
Temperature-driven narrowing of the insulating gap as a precursor of the insulator-to-metal transition: Implications for the electronic structure of solids.
A microscopic picture rationalizing the surprisingly steep decrease in the bandgap with temperature in insulators, crystalline or otherwise is presented and it is shown that possibly with the exception of weakly bound solids made of closed-shell electronic configurations, the existence of an insulating gap or pseudogap in a periodic solid implies that optical phonons must be present, too.
Theory of structural glasses and supercooled liquids.
We review the random first-order transition theory of the glass transition, emphasizing the experimental tests of the theory. Many distinct phenomena are quantitatively predicted or explained by the
Microscopically based calculations of the free energy barrier and dynamic length scale in supercooled liquids: the comparative role of configurational entropy and elasticity.
The temperature dependence of the complexity of a rearranging region is consistent with the picture based on the RFOT theory but is in conflict with the assumptions of the Adam-Gibbs and "shoving" scenarios for the viscous slowing down in supercooled liquids.
