Terahertz third harmonic generation in c-axis LaSrCuO
Kelson Kaj, Kevin A. Cremin, Ian Hammock +3
Terahertz nonlinear optics is a viable method to interrogate collective phenomena in quantum materials spanning ferroelectrics, charge-density waves, and superconductivity. In supe…
Infrared nano-spectroscopy and imaging of collective superfluid excitations in conventional and high-temperature superconductors
H. T. Stinson, J. S. Wu, B. Y. Jiang +8
We investigate near-field infrared spectroscopy and superfluid polariton imaging experiments on conventional and unconventional superconductors. Our modeling shows that near-field…
Response to I. I. Mazin's correspondence on "Electronic correlations in the iron pnictides"
M. M. Qazilbash, J. J. Hamlin, R. E. Baumbach +4
We discuss the discrepancy between the measured optical Drude weight and band structure calculations in LaFePO and other iron-based superconductors. This discrepancy is mostly due…
Infrared signatures of hole and spin stripes in La{2-x}Sr{x}CuO{4}
W. J. Padilla, M. Dumm, Seiki Komiya +2
We investigate the hole and lattice dynamics in a prototypical high temperature superconducting system La{2-x}Sr{x}CuO{4} using infrared spectroscopy. By exploring the anisotropy i…
