From July 31 to August 5th, 2014, two experts in the field of photon-excited STM visited Argonne National Laboratory to discuss recent advances in the field. Hidemi Shigekawa (right) from Tsukuba University presented his work on probing ultrafast spin dynamics with optical pump-probe scanning tunneling microscopy.

Akira Saito (left) offered an overview on the development of synchrotron x-ray scanning tunnling microscopy (SX-STM) at the Japanese light source SPring-8. Together with Volker Rose (center) the reserachers evaluated future potantial collaborations.
