Title: Light-induced new collective modes in the superconductor La 1.905 Ba 0.095 CuO 4

Abstract

Here, we report near and midinfrared pump, c-axis terahertz probe measurements on a superconducting single crystal La 1.905 Ba 0.095 CuO 4 with T c = 32 K. The measurements reveal that the pump-induced change occurs predominantly at the Josephson plasma edge position below T c. Upon excitation by strong near-infrared pulses, the superconducting state is severely disturbed and incoherent quasiparticle excitations develop in the frequency regime above the static plasma edge. However, within a very short time delay (~ 1.5 ps) we observe the reappearance of a very sharp Josephson plasma edge at a frequency lower than the static Josephson plasma edge and the emergence of a new light-induced edge at a higher energy. The results imply that the light can induce new Josephson plasmon modes with different coupling strengths. A similar but weaker effect is observed for the midinfrared pump. No pump-induced effect is detected above T c .
