An inhomogeneous altermagnetic interlayer in a Josephson junction produces enhanced critical current and spin-polarized supercurrent at π misorientation of Néel vectors through cancellation of pair-breaking oscillations.
Supercurrents in superconductor/altermagnet hybrids generate a tunable Néel torque that can propel domain walls and reverse Néel vector orientation.
Gating a finite normal region between a superconducting altermagnet and a metallic reservoir produces perfect nonreciprocal spin and charge currents with tunable polarity via gate voltage and region length.
Precessing magnetization in ballistic S/F/S junctions produces long-range spin-polarized triplet correlations, switching the junction from off to on state with finite Josephson current in fully polarized ferromagnets.
Theoretical calculations for S/F/S Josephson junctions with GdIr2Si2 thin films predict an anomalous phase shift of order unity and a magnetization-tunable Josephson diode effect with efficiency up to 0.3.
Exact diagonalization of a double quantum dot Josephson junction model reveals multiple tunable phase transitions and controllable non-local magnetization driven by on-site and inter-dot electron interactions.
Magnetic flux suppresses doublet and triplet phases while stabilizing singlet states in interacting double quantum dot Josephson junctions, producing flux-controlled current-phase relations and triple points in parameter space.
