Abstract

We demonstrate non-resonant optical control with bi-circular laser fields. Having the pump polarization simultaneously break time and space inversion symmetry allows for switching between K, K’ valleys of MoS₂ even in its inversion symmetric bulk phase. This strong field effect enables a universal and material agnostic approach to valleytronics.
