Nonequilibrium magnons from hot electrons in antiferromagnetic systems

Nonequilibrium magnons from hot electrons in antiferromagnetic systems

We describe a nonthermal magnon activation mechanism in antiferromagnetic (AFM) systems via locally equilibrated spin-unpolarized hot electrons excited by an ultrafast intense laser pulse. We employ a quantum kinetic equation that takes into account a direct electron-magnon scattering channel in eit...
