Abstract

Strong light fields have created opportunities to tailor novel functionalities of solids(1-5). Floquet-Bloch states can form under periodic driving of electrons and enable exotic quantum phases(6-15). On subcycle timescales, lightwaves can simultaneously drive intraband currents(16-29) and interband transitions(18,19,30,31), which enable high-harmonic generation(16,18,19,21,22,25,28-30) and pave ...
