Enhancement of super-exchange pairing in the periodically-driven Hubbard model
J. Coulthard, S. R. Clark, S. Al-Assam +2
Recent experiments performed on cuprates and alkali-doped fullerides have demonstated that key signatures of superconductivity can be induced above the equilibrium critical tempera…
Dynamical decoherence of the light induced interlayer coupling in YBaCuO
C. R. Hunt, D. Nicoletti, S. Kaiser +5
Optical excitation of apical oxygen vibrations in YBaCuO has been shown to enhance its c-axis superconducting-phase rigidity, as evidenced by a transient blue s…
Coherent Modulation of the YBa2Cu3O6+x Atomic Structure by Displacive Stimulated Ionic Raman Scattering
R. Mankowsky, M. Först, T. Loew +3
We discuss the mechanism of coherent phonon generation by Stimulated Ionic Raman Scattering, a process different from conventional excitation with near visible optical pulses. Ioni…
Proposed parametric cooling of bilayer cuprate superconductors by terahertz excitation
S. J. Denny, S. R. Clark, Y. Laplace +2
We propose and analyze a scheme for parametrically cooling bilayer cuprates based on the selective driving of a -axis vibrational mode. The scheme exploits the vibration as a tr…
THz-Frequency Modulation of the Hubbard U in an Organic Mott Insulator
R. Singla, G. Cotugno, S. Kaiser +10
We use midinfrared pulses with stable carrier-envelope phase offset to drive molecular vibrations in the charge transfer salt ET-F2TCNQ, a prototypical one-dimensional Mott insulat…
Pressure dependent relaxation in the photo-excited Mott insulator ETF2TCNQ: Influence of hopping and correlations on quasiparticle recombination rates
M. Mitrano, G. Cotugno, S. R. Clark +12
Femtosecond relaxation of photo-excited quasiparticles in the one dimensional Mott insulator ET-F2TCNQ are measured as a function of external pressure, which is used to tune the el…
Ultrafast strain engineering in complex oxide heterostructures
A. D. Caviglia, R. Scherwitzl, P. Popovich +11
We report on ultrafast optical experiments in which femtosecond mid-infrared radiation is used to excite the lattice of complex oxide heterostructures. By tuning the excitation ene…
