A modulated driven-dissipative oscillator realizes non-Hermitian topological amplification and frequency conversion via a local winding number in synthetic frequency space.
Nonlinear spin conductivity in Floquet non-Hermitian d-wave altermagnets separates into quantum-metric, Berry-curvature and dipole terms and is dominated by the bare quantum metric, with polarization reversing both longitudinal and transverse currents.
