Electromagnonics—the hybridization of spin excitations and electromagnetic waves—has been recognized as a promising candidate for coherent information processing in recent years. Among its various implementations, the lack of available approaches for real-time manipulation on the system dynamics has become a common and urgent limitation. A team of researchers in the US (Argonne National Laboratory, University of Chicago) introduced a fast and uniform modulation technique and demonstrated a series of benchmark coherent gate operations in hybrid magnonics, including semiclassical analogies of Landau-Zener transitions, Rabi oscillations, Ramsey interference, and controlled mode swap operations. Their approach lays the groundwork for dynamical manipulation of coherent signals in hybrid magnonics and can be generalized to a broad range of applications…read more. TECHNICAL ARTICLEÂ
