Incommensurate spin fluctuations and competing pairing symmetries in LaNiO
Han-Xiang Xu, Daniel Guterding
The recent discovery of superconductivity in the bilayer Ruddlesden-Popper nickelate LaNiO under high pressure has generated much interest in the superconducting pairin…
Theory for doping trends in titanium oxypnictide superconductors
Han-Xiang Xu, Daniel Guterding, Harald O. Jeschke
A family of titanium oxypnictide materials BaTi2Pn2O (Pn = pnictogen) becomes superconducting when a charge and/or spin density wave is suppressed. With hole doping, isovalent dopi…
Importance of Fermi surface and magnetic interactions for the superconducting dome in electron doped FeSe intercalates
Makoto Shimizu, Nayuta Takemori, Daniel Guterding +1
The van-der-Waals gap of iron chalcogenide superconductors can be intercalated with a variety of inorganic and organic compounds that modify the electron doping level of the iron l…
Two-dome superconductivity in FeS induced by a Lifshitz transition
Makoto Shimizu, Nayuta Takemori, Daniel Guterding +1
Among iron chalcogenide superconductors, FeS can be viewed as a simple, highly compressed relative of FeSe without nematic phase and with weaker electronic correlations. Under pres…
Basic electronic properties of iron selenide under variation of structural parameters
Daniel Guterding, Harald O. Jeschke, Roser Valenti
Since the discovery of high-temperature superconductivity in the thin-film FeSe/SrTiO system, iron selenide and its derivates have been intensively scrutinized. Using ab initio…
Non-trivial role of interlayer cation states in iron-based superconductors
Daniel Guterding, Harald O. Jeschke, I. I. Mazin +3
Unconventional superconductivity in iron pnictides and chalcogenides has been suggested to be controlled by the interplay of low-energy antiferromagnetic spin fluctuations and the…
Role of vertex corrections in the matrix formulation of the random phase approximation for the multiorbital Hubbard model
Michaela Altmeyer, Daniel Guterding, P. J. Hirschfeld +3
In the framework of a multiorbital Hubbard model description of superconductivity, a matrix formulation of the superconducting pairing interaction that has been widely used is desi…
Near-degeneracy of extended and order parameters in quasi-two-dimensional organic superconductors
Daniel Guterding, Michaela Altmeyer, Harald O. Jeschke +1
The symmetry of the superconducting order parameter in quasi-two-dimensional BEDT-TTF organic superconductors is a subject of ongoing debate. We report ab initio density functional…
Evidence for eight node mixed-symmetry superconductivity in a correlated organic metal
Daniel Guterding, Sandra Diehl, Michaela Altmeyer +10
We report a combined theoretical and experimental investigation of the superconducting state in the quasi-two-dimensional organic superconductor -(ET)Cu[N(CN)]Br. Applyi…
Unified picture of the doping dependence of superconducting transition temperatures in alkali metal/ammonia intercalated FeSe
Daniel Guterding, Harald O. Jeschke, P. J. Hirschfeld +1
In the recently synthesized Li(NH)(NH)FeSe family of iron chalcogenides a molecular spacer consisting of lithium ions, lithium amide and ammonia separat…
Hydrostatic-pressure tuning of magnetic, nonmagnetic and superconducting states in annealed Ca(FeCo)As
E. Gati, S. Köhler, D. Guterding +6
We report on measurements of the magnetic susceptibility and electrical resistance under He-gas pressure on single crystals of Ca(FeCo)As. We find that fo…
