Multipole polaron in the devil's staircase of CeSb
Y. Arai, Kenta Kuroda, T. Nomoto +17
Rare-earth intermetallic compounds exhibit rich phenomena induced by the interplay between localized orbitals and conduction electrons. However, since the energy scale of the c…
Observation of spin-polarized bands and domain-dependent Fermi arcs in polar Weyl semimetal MoTe
M. Sakano, M. S. Bahramy, H. Tsuji +9
We investigate the surface electronic structures of polar 1T'-MoTe2, the Weyl semimetal candidate realized through the nonpolar-polar structural phase transition, by utilizing the…
Multiple-pseudogap phases in hydrogen-doped LaFeAsO system
A. Nakamura, T. Shimojima, T. Sonobe +6
The low energy electronic structure of LaFeAsO1-xHx (0.0 < x < 0.60), the system which exhibits two superconducting domes in its phase diagram, is investigated by utilizing the las…
Pseudogap formation above the superconducting dome in iron-pnictides
T. Shimojima, T. Sonobe, W. Malaeb +29
The nature of the pseudogap in high transition temperature (high-Tc) superconducting cuprates has been a major issue in condensed matter physics. It is still unclear whether the hi…
Three-dimensional bulk band dispersion in polar BiTeI with giant Rashba-type spin splitting
M. Sakano, J. Miyawaki, A. Chainani +12
In layered polar semiconductor BiTeI, giant Rashba-type spin-split band dispersions show up due to the crystal structure asymmetry and the strong spin-orbit interaction. Here we in…
Femtosecond core level photoemision spectroscopy on 1T-TaS2 using 60 eV laser source
K. Ishizaka, T. Kiss, T. Yamamoto +11
Time-resolved photoelectron spectroscopy (trPES) can directly detect transient electronic structure, thus bringing out its promising potential to clarify nonequilibrium processes a…
Laser-excited ultrahigh-resolution photoemission spectroscopy of NaxCoO2.yH2O:Evidence for pseudogap formation
T. Shimojima, T. Yokoya, T. Kiss +9
We have studied the temperature-dependent electronic structure near the Fermi level (EF) of the layered cobaltate superconductor, Na0.35CoO2.1.3H2O, and related materials, using la…
