UL Lafayette Physicist's Latest Paper Reveals Emergent Electrodynamics

Please view Dr. Charilaou's latest publication this year related to his research.  In addition, Dr. Charilaou has received new funding on two successful research proposals. This funding, which is dedicated to pursuing cutting edge research in the magnetic properties of materials, opens exciting research opportunities for Physics undergraduates and graduate students.

This new publication of an international team, including Dr. Charilaou, predicts that the modification of magnetization textures in nanostructures leads to the generation of substantial emergent electrodynamics. The team showed that the annihilation of skyrmions and antiskyrmions involves the creation and rapid motion of magnetic singularities, Bloch points seen in the figure here, and that their motion generates terahertz radiation. The team also predicts ways to control the frequency and amplitude of the radiation by means of engineering defects, paving the way to a new type of spintronic devices.
