Signatures of three-dimensional photo-induced superconductivity in YBa${}_2$Cu${}_3$O${}_{6.48}$

M. Rosenberg, D. Nicoletti, M. Buzzi +5

Optical excitation of large-amplitude apical oxygen phonon oscillations has been shown to renormalize the electronic properties of YBa${}_2$Cu${}_3$O${}_{6+x}$, inducing a superconductin…
