Dielectric and Optical Spectroscopy on Correlated Electron Systems (F05 (B03))

在这个项目中，我们将研究电相关材料在广泛的外部参数范围内的介电，微波，太赫兹和光学响应。我们将寻找新的机制，导致极性秩序和多铁性，并探讨复杂的相互作用的电荷，自旋，轨道和晶格自由度。我们还将专注于多铁性材料的单向透明性，从而实现独特的光学应用。此外，我们的目标是解开物理拓扑保护结构，如skyrmions和铁电畴壁涡核，这两个有前途的新功能，为未来的微电子技术的进步。

In this project, we will investigate the dielectric, microwave, THz, and optical response of electronically correlated materials in a broad range of external parameters. We will search for new mechanisms leading to polar order and multiferroicity and explore the complex interplay of charge, spin, orbital, and lattice degrees of freedom. We will also focus on one-way transparency in multiferroics enabling unique optical applications. Moreover, we aim to unravel the physics of topologically protected structures like skyrmions and ferroelectric domain-wall vortex cores, both promising new functionalities for future advances in microelectronics.
