Clocking the Onset of Bilayer Coherence in a High-${\mathrm{T}}_{\mathrm{C}}$ Cuprate

Edoardo Baldini, Andreas Mann, Benjamin P. P. Mallett +8

In cuprates, a precursor state of superconductivity is speculated to exist above the critical temperature ${\mathrm{T}}_{\mathrm{C}}$. Here we show via a combination of far-infrared ellipsometr…
