This workshop is going to be the fourth in a series held previously at the Max-Planck Institute for the Science of Light, Erlangen 2017, as a SPICE workshop in Mainz 2018, and at the Cavendish Lab., Cambridge 2019 that started after the discovery of strong coupling between photons and magnons. This breakthrough elevated magnons to become alternatives to e.g. photons and phonons as conduits of quantum and classical information. Research on the interaction of photons and magnons is referred to as optomagnonics, cavity spintronics, and spin cavitronics, with increasing inclusiveness with related fields.

This workshop series aims to provide a platform for new developments in the core issues of spin cavitronics. We invite the spintronics and magnetism community since the expertise in magnetic materials and devices is essential. The workshop will also provide interfaces to related fields such as optomechanics, atom optics, quantum optics, and quantum information with similar concepts, goals, and techniques.

The previous workshops helped to consolidate a community interested in exploring quantum coherence of magnons and initiated many collaborations between theoreticians and experimentalists of different disciplines, institutions, and countries. The proposed workshop will preserve this generated momentum and expand the community especially in Japan, which, in spite of many pioneering contributions, is still relatively small.
