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…
Two distinct kinetic regimes for the relaxation of light-induced superconductivity in LaEuSrCuO
C. R. Hunt, D. Nicoletti, S. Kaiser +3
We address the kinetic competition between charge striped order and superconductivity in LaEuSrCuO. Ultrafast optical excitation is tuned to a mid…
Femtosecond x rays link melting of charge-density wave correlations and light-enhanced coherent transport in YBa2Cu3O6.6
M. Först A. Frano, S. Kaiser, R. Mankowsky +11
We use femtosecond resonant soft x-ray diffraction to measure the optically stimulated ultrafast changes of charge density wave correlations in underdoped YBa2Cu3O6.6. We find that…
Optically induced superconductivity in striped La2-xBaxCuO4 by polarization-selective excitation in the near infrared
D. Nicoletti, E. Casandruc, Y. Laplace +7
We show that superconducting interlayer coupling, which coexists with and is depressed by stripe order in La1.885Ba0.115CuO4, can be enhanced by excitation with near-infrared laser…
Optically enhanced coherent transport in YBa2Cu3O6.5 by ultrafast redistribution of interlayer coupling
W. Hu, S. Kaiser, D. Nicoletti +7
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 tech…
Andreev Reflection Like Enhancement Above Bulk in Electron Underdoped Iron Arsenides
H. Z. Arham, C. R. Hunt, J. Gillett +5
We use point contact spectroscopy (PCS) to probe the superconducting properties of electron doped () and hole doped…
Optically induced coherent transport far above Tc in underdoped YBa2Cu3O6+x
S. Kaiser, C. R. Hunt, D. Nicoletti +8
We report on a photo-induced transient state of YBa2Cu2O6+x in which transport perpendicular to the Cu-O planes becomes highly coherent. This effect is achieved by excitation with…
Detection of Orbital Fluctuations Above the Structural Transition Temperature in the Iron-Pnictides and Chalcogenides
H. Z. Arham, C. R. Hunt, W. K. Park +15
We use point contact spectroscopy to probe () and . For we detect orbital fluctuations above while for…
Design of new superconducting materials, and point contact spectroscopy as a probe of strong electron correlations
Laura H. Greene, Hamood Z. Arham, Cassandra R. Hunt +1
At this centenary of the discovery of superconductivity, the design of new and more useful superconductors remains as enigmatic as ever. These materials play crucial roles both for…
Gap-like feature in the normal state of , and revealed by Point Contact Spectroscopy
H. Z. Arham, C. R. Hunt, W. K. Park +12
Point contact spectroscopy reveals a gap-like feature above the magnetic and structural transition temperatures for underdoped , and $Fe_{1+y}T…
Strong Coupling Superconductivity in Iron-Chalcogenide FeTeSe
W. K. Park, C. R. Hunt, H. Z. Arham +6
The superconducting order parameter in the iron-chalcogenide superconductor FeTeSe ( = 14.2 K) is investigated by point-contact Andreev reflection s…
