摘要：

Chiral crystals and molecules were recently predicted to form an intriguing platform for unconventional orbital physics. Here, we report the observation of chirality-driven orbital textures in the bulk electronic structure of CoSi, a prototype member of the cubic B20 family of chiral crystals. Using circular dichroism in soft x-ray angle -resolved photoemission, we demonstrate the formation of a bulk orbital -angularmomentum texture and monopolelike orbital -momentum locking that depends on crystal handedness. We introduce the intrinsic chiral circular dichroism, ic CD, as a differential photoemission observable and a natural probe of chiral electron states. Our findings render chiral crystals promising for spin-orbitronics applications.
