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.

A06(Lang)将通过温度和氦气压力控制的热膨胀和介电测量来研究受挫有机电荷转移盐中电子和弹性自由度之间的紧密耦合。将特别关注围绕Mott转变的临界弹性现象，以及实现和控制新相的可能性，如电子多铁性和电荷玻璃态。将与致力于这些系统的各种实验和理论项目进行强烈的互动。该项目还将为合作项目提供单晶。
