Photoinduced filling of near nodal gap in Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$

Z. Zhang, C. Piovera, E. Papalazarou +5

We report time and angle resolved spectroscopic measurements in optimally doped Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$. The spectral function is monitored as a function of temperature, phot…
