Title: Quantum Transduction and Spin-orbitronics Using Hybrid Magnonic Systems

Abstract: Hybrid magnonic systems have gained increased interest due to their potential impact in quantum transduction and coherent information processing [1]. Magnons, as the fundamental excitation of magnetically ordered materials, exhibit promising features that can be tuned and made to coherently couple to other excitations, such as microwave photons, light, phonons, and other magnons. I will introduce our recent work in the coherent magnon-photon coupling in a permalloy-superconducting resonator device and the magnon-magnon coupling of a permalloy-yttrium iron garnet device [2]. Lastly, I will show how spin-orbit effects [3] can be used as an effective means to both tune and detect the dynamic magnetic properties in magnonic systems [4].

Bio: Wei Zhang received his B.S. in Physics from Peking University, China (2008) and Ph.D. in Materials Science and Engineering from University of Washington – Seattle (2013). He did his postdoc work at Argonne National Laboratory (2013 – 16). He is now an associate professor in Physics at Oakland University in Michigan. His research has been on spintronics and quantum magnonic engineering. He was the recipient of the IEEE Magnetic Society Early Career Award (2016) and NSF CAREER award (2020).
