Dynamical decoherence of the light induced interlayer coupling in YBa${}_2$Cu${}_3$O${}_{6+\delta }$

C. R. Hunt, D. Nicoletti, S. Kaiser +5

Optical excitation of apical oxygen vibrations in YBa${}_2$Cu${}_3$O${}_{6+\delta }$ has been shown to enhance its c-axis superconducting-phase rigidity, as evidenced by a transient blue s…
