Scientific Achievement
Coherent gate operation on the magnon-microwave photon interaction is achieved for the first time.
Significance and Impact
This work demonstrates a novel approach for directly tuning hybrid magnonic dynamics by DC gating, paving the road for practical coherent information processing using magnons in both classical and quantum regimes.
Research Details
- A successful novel gating scheme is shown using a new device design with a fast-responding antenna, allowing the rapid tuning of the magnon-microwave photon interactions.
- The detuning between magnons — quasiparticles representing collective spin excitations — and cavity photons is controlled by DC detuning pulse sequences, enabling fast controls over their interactions.
- The Center for Nanoscale Materials (CNM) magneto-electro-optical spectrometer was used.
Work was performed in part at CNM.
About Argonne’s Center for Nanoscale Materials
The Center for Nanoscale Materials is one of the five DOE Nanoscale Science Research Centers, premier national user facilities for interdisciplinary research at the nanoscale supported by the DOE Office of Science. Together the NSRCs comprise a suite of complementary facilities that provide researchers with state-of-the-art capabilities to fabricate, process, characterize and model nanoscale materials, and constitute the largest infrastructure investment of the National Nanotechnology Initiative. The NSRCs are located at DOE’s Argonne, Brookhaven, Lawrence Berkeley, Oak Ridge, Sandia and Los Alamos National Laboratories.
