Ionization of noble gases by strong infrared circularly-polarized laser pulses can produce electron currents with a controllable degree of spin polarization [1-4]. Spin polarization arises as a consequence of (1) entanglement between the liberated electron and the parent ion, and (2) sensitivity of ionization to the sense of electron rotation in the initial state. In this context, the use of two-color counter-rotating bicircular fields [5] opens new opportunities for introducing the spin degree… 
Selectivity in electron emission induced by ultrashort circularly polarized laser pulses
We theoretically investigate the ionization of neonlike atoms by an intense ultrashort circularly polarized laser pulse as a function of wavelength, spanning the regime from single-photon ionization

Possibility of introducing spin into attoscience with spin-polarized electrons produced by a bichromatic circularly polarized laser field
We show that the electrons, produced in strong-bicircular-field-induced above-threshold ionization of inert-gas atoms, have a large spin asymmetry if the ions exhibit fine-structure splitting. For a

It is shown that for the p ground state of the inert gases used in the experiments, the polarization of the attosecond pulses is close to elliptical, and this is caused by the different intensities of the high harmonics of the opposite helicity.
