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…

Broadband Dielectric and THz Spectroscopy on Bio-Related Matter: Water, Amino Acids, Proteins, and Blood

Peter Lunkenheimer, Sebastian Emmert, Martin Wolf +1

In the present work, we examine the relevance and proper interpretation of broadband-dielectric and THz-spectroscopy data for the investigation of various types of biological matte…

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 corresp…

Post-synthesis tuning of dielectric constant via ferroelectric domain wall engineering

L. Zhou, L. Puntigam, P. Lunkenheimer +7

A promising mechanism for achieving colossal dielectric constants is to use insulating internal barrier layers, which typically form during synthesis and then remain in the materia…
