Twisting harmonics: Transfer of orbital angular momentum in solid-state high-harmonic generation
Debobrata Rajak, Bikash Kumar Das, Rajaram Shrestha +7
Although solid-state platforms underpin modern electronics, little is known about how intense ultrashort light pulses carrying orbital angular momentum (OAM) interact with solids.…
