The Kitaev interaction, found in candidate materials such as α-RuCl_{3}, occurs through the metal (M)-ligand (X)-metal (M) paths of the edge-sharing octahedra because the large spin-orbit coupling (SOC) on the metal atoms activates directional spin

We demonstrate that the introduction of an elemental beam of Mn during the molecular beam epitaxial growth of Bi _2 Se _3 results in the formation of layers of Bi _2 MnSe _4 that intersperse between layers of pure Bi _2 Se _3 . This study revises

The advent of next-generation X-ray free electron lasers will be capable of delivering X-rays at a repetition rate approaching 1 MHz continuously. This will require the development of data systems to handle experiments at these type of facilities, es
