Researchers discover OAM monopoles in chiral topological semi-metals, enabling energy-efficient memory devices in orbitronics.

Researchers at the Paul Scherrer Institute have discovered orbital angular momentum (OAM) monopoles in chiral topological semi-metals, a new class of materials. These materials, characterized by a helical atomic structure, can efficiently generate OAM currents, paving the way for energy-efficient memory devices in the emerging field of orbitronics. This advancement holds promise for reducing the environmental impact of traditional electronics.
