    Photoinduced Studies
    Invited
    A. Cavalleri, S. Kaiser, D. Nicoletti, C. Hunt, M. LeTacon, B. Keimer, T. Takayama, H. Takagi In this talk I will discuss some of our recent work aimed at controlling superconductivity in the High Tc cuprates with light. High-field THz and mid-infrared radiation are used to manipulate low frequency excitations in the superconducting and in the underdoped phases. The first key result...

    Nanoscale Spectroscopies
    Invited
    Peter Hommelhoff, Max Planck Institute of Quantum Optics When femtosecond laser pulses are focused on nanometric metal tips, electrons are emitted. For few-cycle laser pulses, the liberated electronic matter wave can be driven back towards to parent tip when the laser field flips sign. At the tip's surface it can scatter elastically, gain more energy in the laser field, and travel towards...

  3. 156. LIGHT INDUCED MELTDOWN OF QUASIPARTICLES IN HIGH TC SUPERCONDUCTORS
    Alessandra Lanzara (UC Berkeley)
    25/07/2012, 11:45
    Invited
    Alessandra Lanzara Physics Department - University California, Berkeley Materials Science Division, Lawrence Berkeley National Laboratory We use high resolution time- and angle- resolved photoemission spectroscopy (tr-ARPES) to directly probe collective dynamics after optical excitation and study their influence on quasiparticles dynamics, Cooper pair formation, superconducting gap and...
