The 2/3 Rule of Glass Physics Implies Universalities in Crystal Melting
Peter Lunkenheimer, Konrad Samwer, Alois Loidl
Since more than 100 years, melting is thought to be governed by the Lindemann criterion. It assumes that a crystal melts when, upon heating, the growing atomic vibration amplitudes…

Crystal melting influenced by particle cooperativity of the liquid
P. Lunkenheimer, K. Samwer, A. Loidl
Recently, a universal relation between the thermal expansion coefficient of glasses , their glass-transition temperature Tg, and the so-called fragility index m of the corres…

Prigogine-Defay ratio of glassy freezing scales with liquid fragility
Alois Loidl, Peter Lunkenheimer, Konrad Samwer
A detailed study of published experimental data for a variety of materials on the incremental variation of heat capacity, thermal expansion, and compressibility at glassy freezing…
