Understanding the ultrafast dynamics of charge/spin transitions in magnetic insulators (MI) is crucial for developing new materials interfaces for spin-electronics and quantum information science applications. Supported by CEM, the groups of Yang and Baker reported a femtosecond extreme UV (XUV) spectroscopy of yttrium iron garnet (Y3Fe5O12, YIG), one of the important MI garnets for the NM/MI interfaces in this IRG.

The CEM Student Internal Advisory Council advises CEM in the interests of students and postdocs and organizes technical and team-building events. 

The cytoskeletal component actin plays a crucial role in various cellular functions, including cell shape regulation and intracellular transport, by forming filaments and networks. Despite the current understanding of actin's morphological versatility, the impact of crowded environments—specifically how actin filaments organize into bundles and how this organization changes the protein secondary structure—remains under-explored. Here, we used two-dimensional infrared (2D IR) spectroscopy and structure based spectral calculations to map out structural changes of actin filaments under two degrees of crowding and bundling.
