Elastic effects in strongly correlated molecule-based systems with geometrical frustration (A06+)

点击翻译按钮获取中文摘要

A06 (Lang) will investigate the intimate coupling between the electronic and elastic degrees of freedom in frustrated organic charge-transfer salts via thermal expansion and dielectric measurements controlled by of temperature and He-gas pressure. Special attention will be dedicated to the phenomenon of critical elasticity around the Mott transition, and the possibility to realize and control new phases such as electronic multiferroicity and charge-glass states. There will be strong interactions with various experimental and theory projects working on these systems. The project will also supply single crystals to the collaborating projects.
