Description:
Author(s): R. P. S. M. Lobo, G. Chanda, A. V. Pronin, J. Wosnitza, S. Kasahara, T. Shibauchi, and Y. Matsuda 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 penetration depth of 225 nm. No sharp signature of the superconducting gap is observed. This suggests that the system is likely i... [Phys. Rev. B 91, 174509] Published Mon May 11, 2015
