Effective tight-binding model for renormalized band structure of Sr2RuO4
V. B. Zabolotnyy, D. V. Evtushinsky, A. A. Kordyuk +7
We derive an effective quasiparticle tight-binding model which is able to describe with high accuracy the low-energy electronic structure of Sr2RuO4 obtained by means of low temper…
A weak-coupling superconductivity in the electron doped NaFeCoAs is revealed by ARPES
S. Thirupathaiah, D. V. Evtushinsky, J. Maletz +8
We report a systematic study on the electronic structure and superconducting (SC) gaps in electron doped NaFeCoAs superconductor using angle-resolved photoemissio…
Electronic band structure and momentum dependence of the superconducting gap in (Ca, Na)Fe2As2 from angle-resolved photoemission spectroscopy
D. V. Evtushinsky, V. B. Zabolotnyy, L. Harnagea +10
Electronic structure of newly synthesized single crystals of calcium iron arsenide doped with sodium with Tc ranging from 33 to 14 K has been determined by angle-resolved photoemis…
Incommensurate magnetic fluctuations and Fermi surface topology in LiFeAs
J. Knolle, V. B. Zabolotnyy, I. Eremin +12
Using the angle-resolved photoemission spectroscopy (ARPES) data accumulated over the whole Brillouin zone (BZ) in LiFeAs we analyze the itinerant component of the dynamic spin sus…
Strong pairing at iron orbitals in hole-doped BaFeAs
D. V. Evtushinsky, V. B. Zabolotnyy, T. K. Kim +14
Among numerous hypotheses, recently proposed to explain superconductivity in iron-based superconductors [1-9], many consider Fermi surface (FS) nesting [2, 4, 8, 10] and dimensiona…
"Cigar" Fermi surface as a possible requisite for superconductivity in iron-based superconductors
S. V. Borisenko, A. N. Yaresko, D. V. Evtushinsky +14
Recently discovered A-Fe-Se (A - alkali metal) materials have questioned the most popular theories of iron-based superconductors because of their unusual electronic structure [1].…
