Quasiparticle spectrum of the hybrid s+g-wave superconductors YNi_2B_2C and LuNi_2B_2C
Kazumi Maki, Hyekyung Won, Stephan Haas
Recent experiments on single crystals of YNiBC have revealed the presence of point nodes in the superconducting energy gap Delta(k} at k = (1,0,0), (0,1,0), (-1,0,0), and (…
Possible Fulde-Ferrell-Larkin-Ovchinnikov State in CeCoIn_5
Hyekyung Won, Kazumi Maki, Stephan Haas +3
Angular dependent magnetothermal conductivity experiments on CeCoIn_5 indicate that this compound is a d-wave superconductor. In this study, the low-temperature behavior of the upp…
Impurity effects on s+g-wave superconductivity in borocarbides Y(Lu)Ni_2B_2C
Qingshan Yuan, Hong-Yi Chen, H. Won +4
Recently a hybrid s+g-wave pairing is proposed to describe the experimental observation for a nodal structure of the superconducting gap in borocarbide YNiBC and possibly L…
Electronic Raman Spectra of Superconducting Borocarbides
H. Jang, H. Won, K. Maki
Recently we have proposed a s+g-wave model for the superconductivity in borocarbides, YNi2B2C and LuNi2B2C. In the present paper we first summarize thermodynamic properties of s+g-…
Thermal Conductivity in Vortex State of Nodal Superconductors
H. Won, K. Maki
How to determine the symmetry of the superconducting order parameter is one of the important issues in novel superconductors, which include charge conjugated organic superconductor…
