Seeing polarons at a metal oxide surface
Polarons in metal oxides play a key role in processes such as catalysis, high temperature superconductivity, and dielectric breakdown in nanoscale electronics. For this reason, numerous studies have been conducted on technologically relevant oxide materials in which...
When magnetism meets topology
The search for exotic particles is one of the most fascinating pursuits of modern physics. While this area of research is traditionally associated with elementary particles created in high-energy physics, simple ‘quasi-particles’, with sometimes highly unconventional...
Magnetically driven metal-insulator transition in a correlated spin-orbit material
Perhaps the most basic classification of a material is according to whether or not it conducts electricity in response to an applied electric field. However, our understanding of why the metallic state is preferred over the insulating one, or vice versa, is far from...
