Key Points

Intercalated moire systems demonstrate plasmons that are lossless due to electron-phonon coupling effects, and this may revolutionize plasmonic applications.
Lossless plasmons result from the formation of an isolated metallic flat-band in the heterostructures, potentially enhancing material performance.
This analysis uses theoretical predictions to explore the effects of alkali atom intercalation on moire systems, highlighting novel pathways for plasmonics development.
Identifying these lossless phenomena suggests significant implications for future plasmonic technologies and materials engineering.

Implication

Theoretical analysis predicts lossless plasmons in intercalated moire heterostructures with alkali atoms, indicating potential for new applications.

Abstract

We predict that intercalation of Moire heterostructures with alkali atoms can enable plasmons that are lossless to first-order in electron-phonon coupling. This results from the formation of an isolated metallic flat-band.
