HIGHLIGHTS
- who: Andrey Baydin from the DepartmentRice University, Houston, Texas, USA have published the article: Magnetically tuned continuous transition from weak to strong coupling in terahertz magnon polaritons, in the Journal: (JOURNAL) of 20/03/2023
- what: The authors demonstrate in situ tuning of g by an external magnetic_field (H) for propagating bulk magnon-polaritons in the antiferromagnetic state of yttrium orthoferrite (YFeO3 ). The model shows that the coupling rate g continuously increases with increasing H, and exact couplingdissipation compensation (C=1) occurs at the critical field, which is the exceptional point in this system. Because . . .
