报告摘要： Cavity spintronics is a newly developing, interdisciplinary field that brings together microwave and optical communities with researchers in spintronics and magnetism. The field started around 2014 when it was found that ferromagnets in cavities hybridize with both microwaves and light by light-matter interaction. Since then, the emergence of cavity spintronics has attracted broad interest from groups studying quantum electrodynamics, cavity polaritons, optomechanics, superconductivity, plasmonics, and phononics. At the center stage of the topic is the physics of magnon-photon coupling: Via the quantum physics of spin-photon entanglement on the one hand and classical electrodynamic coupling on the other, magnon-photon coupling connects some of the most exciting concepts in modern physics, such as quantum information and quantum optics, with one of the oldest sciences on earth, magnetism. This talk aims to provide an introduction to this new frontier of condensed matter physics to researhers working in magnetism, spintronics, quantum information, and microwave technologies. The talk starts with a historical review, tracing this new field back to some of the most courageous work in the history of magnetism, spintronics, cavity quantum electrodynamics, and polaritons. Recent experiments focusing on the development of new cavity-mediated techniques, such as coupling of magnetic moments, distant manipulation of spin current, qubit-magnon coupling, and conversion between optical and microwave photons, will be highlighted.

报告人简介： Can-Ming Hu graduated in 1988 from Fudan University in China. He received his doctorate degree in 1995 from Wuerzburg University in Germany. He became a full professor at University of Manitoba, Canada in 2012.Prof. Hu has published over 130 technical articles in peer-reviewed journals, including book chapters and invited review articles. He has given about 100 invited presentations on semiconductor physics, spintronics, magnetism, and microwave technologies. He co-organized several international workshops: Spin Mechanics IV (Canada, 2017), Magnetic North III (Canada, 2012), Magnetic North I (Canada, 2010), and International Symposium on Quantum Hall Systems and Quantum Materials (Germany, 2004).
