Fermi surface and topology of multiband superconductor BeAu
Riccardo Vocaturo, Klaus Koepernik, Dániel Varjas +3
The chiral material BeAu was recently identified as a multiband type-I superconductor with a critical temperature of 3.2 K. As a member of the B20 crystal family (space group $P2_1…
Diode effect in microwave irradiated Josephson junctions with Yu-Shiba-Rusinov states
Aritra Lahiri, Marcel Polák, Björn Trauzettel
We investigate the critical current in microwave-irradiated Josephson junctions hosting Yu-Shiba-Rusinov states due to magnetic impurities. Under two conditions, namely, (i) the br…
Altermagnetism Induced Bogoliubov Fermi Surfaces Form Topological Superconductivity
Bo Fu, Chang-An Li, Björn Trauzettel
We propose a novel type of topological superconductivity based on Bogoliubov Fermi surfaces (BFSs) in an altermagnetic topological insulator proximitized by an s-wave superconducto…
Magnetic field-bias current interplay in HgTe-based three-terminal Josephson junctions
J. Thieme, W. Himmler, F. Dominguez +8
We investigate HgTe/Nb-based three-terminal Josephson junctions in T-shaped and X-shaped geometries and their critical current contours (CCCs). By decomposing the CCCs into the con…
Mechanism for Nodal Topological Superconductivity on PtBi Surface
Kristian Mæland, Giorgio Sangiovanni, Björn Trauzettel
Experiments show that the Weyl semimetal PtBi hosts unconventional superconductivity in its topological surface states. Hence, the material is a candidate for intrinsic topolog…
Point-contact enhanced superconductivity in trigonal PtBi2: quest for the origin of high-Tc
O. E. Kvitnitskaya, L. Harnagea, G. Shipunov +6
We studied enhanced superconductivity in point contacts (PCs) based on a type-I Weyl semimetal trigonal t-PtBi2 using both normal metal (Ag, Cu, Pt) and ferromagnetic (Fe, Co, Ni)…
