We are happy to announce the new edition of the 'Spins, waves and Interactions' workshop. It will take place 28-30th August 2023 in Greifswald. This year's edition will cover topics from altermagnetism to magnonics and ultrafast spin dynamics. We aim to bring together renowned researchers as well as the rising talents, and to provide a very informal platform for interactions and networking. The invited talks are accompanied by contributed poster presentations.
