So far, selective excitation of a desired valley in the Brillouin zone of ahexagonal two-dimensional material has relied on using circularly polarizedfields. We theoretically demonstrate a way to induce, control, and read valleypolarization in hexagonal 2D materials on a few-femtosecond timescale using afew-cycle, linearly polarized pulse with controlled carrier-envelope phase. Thevalley pseudospin is encoded in the helicity of the emitted high harmonics ofthe driving pulse, allowing one to avoid additional probe pulses and permittingone to induce, manipulate and read the valley pseudospin all-optically, in onestep. High circularity of the harmonic emission offers a method to generatehighly elliptic attosecond pulses with a linearly polarized driver, in anall-solid-state setup.
