Altermagnetic spin textures coupled to superconductors: Domain wall spin-triplet superconductivity and supercurrent-induced torques
Yasir Dar, Mathias S. Scheurer, Constantin Schrade
Motivated by the absence of sizable stray fields and the recently discovered highly non-trivial impact of altermagnetic textures on itinerant electrons, we here study the form of C…
Finite-momentum superconductivity from chiral bands in twisted MoTe
Yinqi Chen, Cheng Xu, Yang Zhang +1
A recent experiment has reported unconventional superconductivity in twisted bilayer MoTe, emerging from a normal state that exhibits a finite anomalous Hall effect -- a signat…
Intrinsic superconducting diode effect and nonreciprocal superconductivity in rhombohedral graphene multilayers
Yinqi Chen, Mathias S. Scheurer, Constantin Schrade
Recent experiments have revealed that superconductivity in rhombohedral tetralayer graphene can emerge from a valley-polarized and, hence, chiral normal state. The interplay of pai…
Percolative supercurrent in superconductor-ferromagnetic insulator bilayers
A. Maiani, A. C. C. Drachmann, L. Galletti +4
We report tunneling spectroscopy and transport measurements in superconducting Al and ferromagnetic-insulator EuS bilayers. The samples display remanent spin-splitting, roughly hal…
Tuning the Josephson diode response with an ac current
Rubén Seoane Souto, Martin Leijnse, Constantin Schrade +3
Josephson diodes are superconducting elements that show an asymmetry in the critical current depending on the direction of the current. Here, we theoretically explore how an altern…
Charge-4e supercurrent in a two-dimensional InAs-Al superconductor-semiconductor heterostructure
Carlo Ciaccia, Roy Haller, Asbjørn C. C. Drachmann +4
Superconducting qubits with intrinsic noise protection offer a promising approach to improve the coherence of quantum information. Crucial to such protected qubits is the encoding…
Supercurrent reversal in ferromagnetic hybrid nanowire Josephson junctions
D. Razmadze, R. Seoane Souto, L. Galletti +7
We report supercurrent transport measurements in hybrid Josephson junctions comprised of semiconducting InAs nanowires with epitaxial ferromagnetic insulator EuS and superconductin…
Nematic, chiral and topological superconductivity in transition metal dichalcogenides
Constantin Schrade, Liang Fu
We introduce and study a realistic model for superconductivity in twisted bilayer WSe, where electron pairing arises from spin-valley fluctuations in the weak-coupling regime…
