Edge polaritons at metal-insulator boundaries in a phase separated correlated oxide
Weiwei Luo, Adrien Bercher, Claribel Dominguez +4
Correlated transition metal oxides, such as cuprates, nickelates, and manganites, are typically considered "bad metals", where high electromagnetic losses suppress the conventional…

Low-loss far-infrared surface phonon polaritons in suspended SrTiO3 nanomembranes
Konnor Koons, Hans A. Bechtel, Javier Taboada-Gutiérrez +6
Phonon polaritons (PhPs), excitations arising from the coupling of light with lattice vibrations, enable light confinement and local field enhancement, which is essential for vario…

Broad Spectral Tuning of Ultra-Low Loss Polaritons in a van der Waals Crystal by Intercalation
Javier Taboada-Gutiérrez, Gonzalo Ãlvarez-Pérez, Jiahua Duan +17
Phonon polaritons (PhPs) -- light coupled to lattice vibrations -- in polar van der Waals (vdW) crystals are promising candidates for controlling the flow of energy at the nanoscal…
