The article reviews the emerging field of orbitronics, which focuses on the manipulation of orbital angular momentum (OAM) in solids. It highlights recent theoretical and experimental advancements that have revealed the nonvanishing OAM in solids under external electric fields, even without spin-orbit coupling. The review discusses the orbital Rashba effect, orbital Edelstein effect (OEE), and orbital Hall effect (OHE), and their implications for spintronics. It also explores the challenges and future directions in harnessing OAM for spintronics, including the need to minimize OAM loss to the lattice and the potential of topological insulators and semimetals. The article emphasizes the importance of understanding OAM relaxation mechanisms and the quantum nature of orbital transport, as well as the potential of orbitronics in quantum information processing and interdisciplinary studies.The article reviews the emerging field of orbitronics, which focuses on the manipulation of orbital angular momentum (OAM) in solids.
