Switching of band inversion and topological surface states by charge density wave
N. Mitsuishi, Y. Sugita, M. S. Bahramy +14
Topologically nontrivial materials host protected edge states associated with the bulk band inversion through the bulk-edge correspondence. Manipulating such edge states is highly…
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…
Orbital anisotropy underlying the superconducting dome in BaFe(AsP) superconductors
T. Sonobe, T. Shimojima, A. Nakamura +8
We investigate the in-plane anisotropy of Fe 3d orbitals occurring in a wide temperature and composition range of BaFe2(As1-xPx)2 system. By employing the angle-resolved photoemiss…
Momentum-dependent sign-inversion of orbital polarization in superconducting FeSe
Y. Suzuki, T. Shimojima, T. Sonobe +14
We investigate the electronic reconstruction across the tetragonal-orthorhombic structural transition in FeSe by employing polarization-dependent angle-resolved photoemission spect…
Lifting of xz/yz orbital degeneracy at the structural transition in detwinned FeSe
T. Shimojima, Y. Suzuki, T. Sonobe +14
We study superconducting FeSe (Tc = 9 K) exhibiting the tetragonal-orthorhombic structural transition (Ts = 90 K) without any antiferromagnetic ordering, by utilizing angle-resolve…
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…
