2D spin-antiferroelectric altermagnets such as monolayer (CoCl)2Te are predicted to show giant spin splitting with spin currents switchable by in-plane electric field angle when hole-doped or gate polarity when electron-doped.
Monolayer CrCX3 and Janus Cr2C2S3Se3 compounds realize 2D higher-order topological insulator phases protected by C3 symmetry, hosting corner states with fractional charges even under spin-orbit coupling.
Supercurrents in superconductor/altermagnet hybrids generate a tunable Néel torque that can propel domain walls and reverse Néel vector orientation.
PT-symmetric antiferromagnets with hidden dipoles allow electric fields to induce up to 20 meV chiral magnon splitting in Cr2CCl2 and Cr2CBr2, enabling reversible switching of magnon spin currents.
Field-free transverse Josephson diode effect and unidirectional transverse supercurrents are predicted in four-terminal junctions made of an altermagnet and Rashba spin-orbit coupled region.
Helicity-resolved Raman and DFT+U plus linear spin-wave theory show plaid-like magnon spin splitting and chirality in MnTe2 dictated by its sublattice symmetries.
Green's function calculation of third-order resistivity corrections in a quadratic-spin-texture 2DEG with Kondo impurities shows strong suppression of TK and a critical alpha_cr for Kondo collapse.
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.
Multipole analysis of α-MnTe shows that distinct altermagnetic configurations induce spin-momentum locking with different parities and magnetic spin Hall effects with up to 16% angle, enabling identification of order parameters via anisotropy.
Magnetic instabilities in generic two-orbital systems are governed by the full interplay of the bare susceptibility tensor and spin interaction matrix, not solely by the quantum geometry of a single-channel susceptibility.
