Effect of the sample work function on alkali metal dosing induced electronic structure change
Saegyeol Jung, Yukiaki Ishida, Minsoo Kim +10
Alkali metal dosing (AMD) has been widely used as a way to control doping without chemical substitution. This technique, in combination with angle resolved photoemission spectrosco…
Optical evidence of local and itinerant states in Ce- and Yb-heavy-fermion compounds
Shin-ichi Kimura, Yong Seung Kwon, Cornelius Krellner +1
The electronic properties of Cerium (Ce) and ytterbium (Yb) intermetallic compounds may display a more local or more itinerant character depending on the interplay of the exchange…
Evidence for a preformed Cooper pair model in the pseudogap spectra of a Ca10(Pt4As8)(Fe2As2)5 single crystal with a nodal superconducting gap
Yu-il Seo, Woo-jae Choi, Shin-ichi Kimura +1
For high-Tc superconductors, clarifying the role and origin of the pseudogap is essential for understanding the pairing mechanism. Among the various models describing the pseudogap…
Thermal activation energy of 3D vortex matter in NaFe1-xCoxAs (x=0.01, 0.03 and 0.07) single crystals
W. J. Choi, Y. I. Seo, D. Ahmad +1
We report on the thermally activated flux flow dependency on the doping dependent mixed state in NaFe1-xCoxAs (x=0.01, 0.03, and 0.07) crystals using the magnetoresistivity in the…
Incarnation of Majorana Fermions in Kitaev Quantum Spin Lattice
Seung-Hwan Do, Sang-Youn Park, Junki Yoshitake +10
Kitaev quantum spin liquid is a topological magnetic quantum state characterized by Majorana fermions of fractionalized spin excitations, which are identical to their own antiparti…
Optical properties of the optimally doped CaLa(PtAs)(FeAs) single crystal
Yu-il Seo, Woo-Jae Choi, Shin-ich Kimura +2
We have measured the reflectivity of the optimally doped CaLa(PtAs)(FeAs) single crystal ( = 32.8K) over the broad frequency range from 4…
