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.
Static lattice distortions from adiabatic electron-phonon coupling act as a tuning knob that alters the magnitude, anisotropy, phase, and chirality of noncollinear RKKY couplings in Rashba d-wave altermagnets.
Rectangular d-wave altermagnets acquire net spin polarization from geometry-induced imbalance in occupied spin states via anisotropic Fermi contours and finite-size k-space sampling, vanishing when Lx equals Ly or in the thermodynamic limit.
Slow phonons suppress the spin Edelstein effect in strained Rashba d-wave altermagnets through energy renormalization that collapses the Fermi surface, producing tunable anisotropic depolarization.
Altermagnetic sublattice order imposes momentum-dependent nodes in the superconducting gap for local pairing interactions and favors nonunitary equal-spin triplet superconductivity at large spin splitting.
Theoretical prediction of a field-free transverse Josephson diode effect with high efficiency and tunability in altermagnets with Rashba coupling.
