Confinement of superconducting fluctuations due to emergent electronic inhomogeneities
C. Carbillet, S. Caprara, M. Grilli +11
The microscopic nature of an insulating state in the vicinity of a superconducting state, in the presence of disorder, is a hotly debated question. While the simplest scenario prop…
Optical Conductivity Evidence of Clean-Limit Superconductivity in LiFeAs
R. P. S. M. Lobo, G. Chanda, A. V. Pronin +4
We measured the optical conductivity of superconducting LiFeAs. In the superconducting state, the formation of the condensate leads to a spectral-weight loss and yields a penetrati…
Interplay between density and superconducting quantum critical fluctuations
S. Caprara, N. Bergeal, J. Lesueur +1
We consider the case of a density-driven metal-superconductor transition in the proximity of an electronic phase separation. In particular we investigate the interplay between supe…
Anomalous phonon redshift in K-doped BaFe2As2 iron pnictides
B. Xu, Y. M. Dai, B. Shen +9
The effect of K, Co and P dopings on the lattice dynamics in the BaFeAs system is studied by infrared spectroscopy. We focus on the phonon at 253 cm, the high…
