Since 2019, when the latest family of Kagome metals was discovered, physicists have been working to better understand their properties and potential applications. A new study led by Assistant Professor of Physics Guangxin Ni focuses on how a particular Kagome metal interacts with light to generate what are known as plasmon polaritons —-level linked waves of electrons and electromagnetic fields in a material, typically caused by light or other electromagnetic waves.
“What makes CsV3Sb5 interesting is how it interacts with light on a very small scale, what’s known as nano-optics,” said lead author Hossein Shiravi, a graduate research assistant at the FSU-headquartered National High Magnetic Field Laboratory The CsV3Sb5 metal was a promising choice for plasmon research because of its unusual electronic and optical properties, such as its potential ability to force waves of plasmons to move in a single direction, to name just one. Recent advances in imaging technology at the nano-scale level helped the researchers complete their work.
