The Center for Discovery and Innovation at City College of New York and the Physics Department have made an announcement regarding the creation of a new type of magnetic quasiparticle. This new type of magnetic quasiparticle is generated by coupling light to a stack of ultrathin two-dimensional magnets. This innovative discovery, which was made possible through a partnership with the University of Texas at Austin, provides the groundwork for a newly developing method to artificially engineer materials by guaranteeing that they have a strong interaction with light.
Vinod M. Menon, a physicist at CCNY and the leader of the research team that conducted the work, stated that “Implementing our approach with magnetic materials offers a viable road towards efficient magneto-optical effects.” “Achieving this aim can enable the use of these materials for applications in common equipment like lasers, as well as for the digital storage of data.” According to Dr. Florian Dirnberger, who is the lead author of the study, the researchers believe that their work uncovered a mostly uncharted realm of powerful interactions between light and magnetic crystals. “Research in recent years brought up a number of atomically flat magnets that are extraordinarily well-suited to be investigated by our methodology,” he remarked. “Our method is exceptionally well-suited to study these atomically flat magnets.”
In the future, the group intends to broaden the scope of these experiments in order to gain a better comprehension of the part that the quantum electrodynamical vacuum plays when quantum materials are positioned inside optical cavities. “Our work paves the way for the stabilization of novel quantum phases of matter that have no counterpart in thermodynamic equilibrium,” said Edoardo Baldini, an assistant professor at The University of Texas at Austin. “Our work paves the way for the stabilization of novel quantum phases of matter that have no counterpart in thermodynamic equilibrium.”
