Superconductivity in spin- systems: symmetry classification, odd-frequency pairs, and Bogoliubov Fermi surfaces
Paramita Dutta, Fariborz Parhizgar, Annica M. Black-Schaffer
The possible symmetries of the superconducting pair amplitude is a consequence of the fermionic nature of the Cooper pairs. For spin- systems this leads to the $\mathcal{SPOT}…
Dia- and paramagnetic Meissner effect from odd-frequency pairing in multi-orbital superconductors
Fariborz Parhizgar, Annica M. Black-Schaffer
The Meissner effect is one of the defining properties of superconductivity, with a conventional superconductor completely repelling an external magnetic field. In contrast to this…
Highly tunable magnetic coupling in ultrathin topological insulator films due to impurity resonances
Mahroo Shiranzaei, Jonas Fransson, Annica M. Black-Schaffer +1
We theoretically investigate the exchange interaction between magnetic impurities in ultrathin BiSe topological insulator films by taking into account the low-energy states…
Finite bulk Josephson currents and chirality blockade removal from inter-orbital pairing in magnetic Weyl semimetals
Paramita Dutta, Fariborz Parhizgar, Annica M. Black-Schaffer
Magnetic Weyl semimetals (WSMs) have been presumed to be immune to proximity-induced spin-singlet superconducting pairing due to a chirality blockade of the regular Andreev reflect…
Odd-frequency superconductivity and Meissner effect in the doped topological insulator BiSe
Johann Schmidt, Fariborz Parhizgar, Annica M. Black-Schaffer
Doped BiSe is proposed to be a nematic superconductor originating from unusual inter-orbital pairing. We classify all induced superconducting pair correlations in BiSe$…
Large Josephson current in Weyl nodal loop semimetals due to odd-frequency superconductivity
Fariborz Parhizgar, Annica M. Black-Schaffer
Weyl nodal loop semimetals (WNLs) host a closed nodal line loop Fermi surface in the bulk, protected zero-energy flat band, or drumhead, surface states, and strong spin-polarizatio…
