Magic angle of SrRuO: Optimizing correlation-driven superconductivity
Jonas B. Profe, Luke C. Rhodes, Matteo Dürrnagel +8
Understanding of unconventional superconductivity is crucial for engineering materials with specific order parameters or elevated superconducting transition temperatures. However,…
Chiral surface superconductivity in half-Heusler semimetals
Tilman Schwemmer, Domenico Di Sante, Jörg Schmalian +1
We propose the metallic and weakly dispersive surface states of half-Heusler semimetals as a possible domain for the onset of unconventional surface superconductivity ahead of the…
Hybrid s-wave superconductivity in CrB
Sananda Biswas, Andreas Kreisel, Adrian Valadkhani +5
In a metal with multiple Fermi pockets, the formation of s-wave superconductivity can be conventional due to electron-phonon coupling or unconventional due to spin fluctuations. We…
Hyperbolic fringe signal for twin impurity quasiparticle interference
Peize Ding, Tilman Schwemmer, Ching Hua Lee +2
We study the quasiparticle interference (QPI) pattern emanating from a pair of adjacent impurities on the surface of a gapped superconductor (SC). We find that hyperbolic fringes (…
Van Hove tuning of AV3Sb5 kagome metals under pressure and strain
Armando Consiglio, Tilman Schwemmer, Xianxin Wu +5
From first-principles calculations, we investigate the structural and electronic properties of the kagome metals AV3Sb5 (A = Cs, K, Rb) under isotropic and anisotropic pressure. Ch…
Triplet Superconductivity from Nonlocal Coulomb Repulsion in an Atomic Sn Layer Deposited onto a Si(111) Substrate
Sebastian Wolf, Domenico Di Sante, Tilman Schwemmer +2
Atomic layers deposited on semiconductor substrates introduce a platform for the realization of the extended electronic Hubbard model, where the consideration of electronic repulsi…
Nature of unconventional pairing in the kagome superconductors AVSb
Xianxin Wu, Tilman Schwemmer, Tobias Müller +10
The recent discovery of AVSb (A=K,Rb,Cs) has uncovered an intriguing arena for exotic Fermi surface instabilities in a kagome metal. Among them, superconductivity is found…
From high- to low-: Multi-orbital effects in transition metal oxides
Michael Klett, Tilman Schwemmer, Sebastian Wolf +8
Despite the structural resemblance of certain cuprate and nickelate parent compounds there is a striking spread of among such transition metal oxide superconductors. We adopt…
Robust -wave superconductivity of infinite-layer nickelates
Xianxin Wu, Domenico Di Sante, Tilman Schwemmer +4
Motivated by the recent observation of superconductivity in strontium doped NdNiO, we study the superconducting instabilities in this system from various vantage points. Starti…
