Josephson anomalous vortices
Dan Crawford, Stefan IliÄ, Pauli Virtanen +1
We show that vortices with circulating current, related with odd-frequency triplet pairing, appear in Josephson junctions where the barrier is a weak ferromagnet with strong spin-o…
Gate-tunable polarity inversions and three-fold rotation symmetry of the superconducting diode effect
William F. Schiela, Melissa Mikalsen, Daniel Crawford +4
The superconducting diode effect is an asymmetry in the critical current with respect to the supercurrent polarity. One impetus driving recent interest in the effect is its depende…
Characterizing Dynamic Majorana Hybridization for Universal Quantum Computing
Themba Hodge, Eric Mascot, Dan Crawford +1
Qubits built out of Majorana zero modes (MZMs) have long been theorized as a potential pathway toward fault-tolerant topological quantum computation. Almost unavoidable in these pr…
Preparation and readout of Majorana qubits in magnet-superconductor hybrid systems
Dan Crawford, Roland Wiesendanger, Stephan Rachel
Initializing the ground state of a quantum bit (qubit) based on Majorana zero modes is one of the most pressing issues for future topological quantum computers. We explore a protoc…
