Possible Eliashberg-type superconductivity enhancement effects in a two-band superconductor MgB2 driven by narrow-band THz pulses
Sergei Sobolev, Amon Lanz, Tao Dong +12
We study THz-driven condensate dynamics in epitaxial thin films of MgB, a prototype two-band superconductor (SC) with weak interband coupling. The temperature and excitation…
Revealing the frequency-dependent oscillations in the nonlinear terahertz response induced by the Josephson current
Sijie Zhang, Zhiyuan Sun, Qiaomei Liu +11
Nonlinear responses of superconductors to intense terahertz radiation has been an active research frontier. Using terahertz pump-terahertz probe spectroscopy, we investigate the c-…
Fano interference of the Higgs mode in cuprate high-Tc superconductors
Hao Chu, Sergey Kovalev, Zi Xiao Wang +31
Despite decades of search for the pairing boson in cuprate high-Tc superconductors, its identity still remains debated to date. For this reason, spectroscopic signatures of electro…
Optical spectroscopy study of charge density wave order in SrRhSn and (SrCa)RhSn
W. J. Ban, H. P. Wang, C. W. Tseng +3
We perform optical spectroscopy measurement across the charge density wave (CDW) phase transitions on single-crystal samples of SrRhSn and (SrCa)…
Observation of a ubiquitous three-dimensional superconducting gap function in optimally-doped BaKFeAs
Y. -M. Xu, Y. -B. Huang, X. -Y. Cui +10
The iron-pnictide superconductors have a layered structureformed by stacks of FeAs planes from which the superconductivity originates. Given the multiband and quasi three-dimension…
Band Structure and Fermi Surface of an Extremely Overdoped Iron-Based Superconductor KFe2As2
T. Sato, K. Nakayama, Y. Sekiba +8
We have performed high-resolution angle-resolved photoemission spectroscopy on heavily overdoped KFe_2As_2 (transition temperature (Tc = 3 K). We observed several renormalized band…
Multiple Nodeless Superconducting Gaps in (Ba0.6K0.4)Fe2As2 Superconductor from Angle-Resolved Photoemission Spectroscopy
Lin Zhao, Haiyun Liu, Wentao Zhang +15
High resolution angle-resolved photoemission measurements have been carried out to study the superconducting gap in the (Ba0.6K0.4)Fe2As2 superconductor with Tc=35 K. Two hole-like…
