Enhancing spin polarization using ultrafast angular streaking
Armstrong G. S. J.; Clarke D. D. A.; Benda J.; Wragg, J.; Brown A.C.; van der Hart H. W.
Through solution of the multielectron, semirelativistic, time-dependent Schrodinger equation, we show that angular streaking produces strongly spin-polarized electrons in a noble gas. The degree of spin polarization increases with the Keldysh parameter, so that angular streaking-ordinarily applied to investigate tunnelingmay be repurposed to generate strongly spin-polarized electron bunches. Additionally, we explore modifications of the angular streaking scheme that also enhance spin polarization.
