Two-channel point-contact tunneling theory of superconductors
Mikael Fogelstrom, Matthias J. Graf, V. A. Sidorov +3
We introduce a two-channel tunneling model to generalize the widely used BTK theory of point-contact conductance between a normal metal contact and superconductor. Tunneling of ele…
Evolution of quasiparticle states with and without a Zn-impurity in doped 122 iron pnictides
Lihua Pan, Jian Li, Yuan-Yen Tai +3
Based on a minimal two-orbital model [Tai {\it et al.}, Europhys. Lett. \textbf{103}, 67001 (2013)], which captures the canonical electron-hole-doping phase diagram of the iron-pni…
Emergent topological mirror insulator in t2g-orbital systems
Yuan-Yen Tai, Cheng-Ching Joseph Wang, Matthias J. Graf +2
The electronic band structure of iron pnictides exhibits four Dirac cones, which are due to crystal symmetry and orbital bonding orientation. This hallmark signature presents the p…
Fermi surface evolution and checker-board block-spin antiferromagnetism in FeSe
Yuan-Yen Tai, Jian-Xin Zhu, Matthias J. Graf +1
We develop an effective multiorbital mean-field t-J Hamiltonian with realistic tight-binding and exchange parameters to describe the electronic and magnetic structures of iron-sele…
Role of Fermi surface anisotropy in the study of gap anisotropy using magnetic-field-angle dependence of thermal oscillations in AyFe2-xSe2 superconductors
Tanmoy Das, Anton B. Vorontsov, Ilya Vekhter +1
We present a numerical study of the field-angle resolved oscillations of the thermal conductivity and specific heat under rotated magnetic field in the FeSe [=K…
Point-contact spectroscopy in heavy-fermion superconductors
Mikael Fogelström, W. K. Park, L. H. Greene +2
We develop a minimal model to calculate point-contact spectra between a metallic tip and a superconducting heavy-fermion system. We apply our tunneling model to the heavy fermion C…
