Spin qubits in altermagnetic quantum dots get a field-free, ellipticity-tunable splitting, a complete electrical gate set, and noise channels that cause relaxation rather than dephasing.
Altermagnets exhibit a resonant third-order intrinsic anomalous Hall effect from the Berry curvature quadrupole, serving as a quantum geometric transport fingerprint.
Cr doping of FeSb2 breaks time-reversal symmetry with bulk short-range spin-compensated order below ~3.5 K but does not stabilize long-range collinear altermagnetic order.
Altermagnets enable planar Josephson junctions that host Majorana end modes controlled by crystallographic orientation, extending naturally to high-Tc platforms.
Ferromagnetic Ni contacts enable anomalous and nonlinear Hall effects in centrosymmetric CrSb, with Hall-slope sign inversion and bow-tie hysteresis attributed to bulk altermagnetism plus topological surface states.
Strain engineering drives altermagnetic-to-ferrimagnetic transitions and activates anomalous transport responses in RuO2 and MnF2 via symmetry breaking.
In a 2D model Hamiltonian, orbital Hall conductivity quantizes when altermagnetism exceeds sp-hybridization while spin Hall quantizes when Rashba SOC is weaker, with both independent of the other coupling and arising from Fermi-surface Berry curvature.

Quantized orbital and spin Hall transport: interplay between $sp$-hybridization, altermagnetism and spin-orbit coupling
In a 2D model Hamiltonian, orbital Hall conductivity quantizes when altermagnetism exceeds sp-hybridization while spin Hall quantizes when Rashba SOC is weaker, with both independent of the other coupling and arising from Fermi-surface Berry curvature.
