Terahertz Metamaterial Renormalization of Superconducting Josephson Plasmons in La${}_{1.85}$Sr${}_{0.15}$CuO${}_4$

Kelson Kaj, Ian Hammock, Chunxu Chen +8

We investigate light-matter coupling in the cuprate superconductor La${}_{1.85}$Sr${}_{0.15}$Cu0${}_4$ (LSCO), accomplished by adhering metamaterial resonator arrays (MRAs) to a c-axis o…
