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。我们将寻找导致极性有序和多铁性的新机制，并探索电荷、自旋、轨道和晶格自由度的复杂相互作用。我们还将专注于实现独特光学应用的多铁性中的单向透明度。此外，我们的目标是揭开诸如Skyrmions和铁电磁区-壁涡旋核等拓扑保护结构的物理原理，这两种结构都有望为未来微电子学的发展提供新的功能。

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.
