University of British Columbia (UBC) scientists have demonstrated a reversible way to switch the topological state of a quantum material using mechanisms compatible with modern electronic devices. Published in Nature Materials, the study offers a new route toward more energy efficient electronics based on topologically protected currents rather than conventional charge flow.Quantum Physics NewsRead More

In physical systems, transport takes many forms, such as electric current through a wire, heat through metal, or even water through a pipe. Each of these flows can be described by how easily the underlying quantity—charge, energy, or mass—moves through a material.Quantum Physics NewsRead More

Researchers at the University of Twente and Utrecht University demonstrated for the first time that quantum states in the ultra-narrow material germanene can be switched on and off using only an electric field. The researchers were able to vary the electric field strength very precisely, causing the special ‘topological’ states in nanoribbons to disappear or
