    Enhancement of Superconducting Coherence in YBa2Cu3O x by Resonant Lattice Excitation

    By using femtosecond pulses in the mid-infrared, we resonantly excite an infrared-active phonon mode in the high-temperature superconductor YBa2Cu3O x . The electronic properties...

    Optically enhanced coherent transport in YBa2Cu3O6.5 by ultrafast redistribution of interlayer coupling

    Nonlinear optical excitation of infrared active lattice vibrations has been shown to melt magnetic or orbital orders and to transform insulators into metals. In cuprates, this technique has been used to remove...
