Ultrafast spin dynamics lab(USDL) is a research group led by Prof. Kabjin Kim of KAIST, currently research on spintronics and magnetism.

'Condensed matter physics' is intriguing field of physics all the time for the history of physics but nature seems to enjoy surprising us with incalculable complexity of many-body physics. However, there are many numbers that describes nature, and one of most important number is spin, which is directly connected to magnetism. We are trying to see and understand phenomena related to spin in condensed matter, especially dynamic ones.
