With the rapid advancement of attosecond science, the intrinsic timescale of electronic dynamics in atoms, molecules and solids can now be accessed. Integrating attosecond techniques with conventional scanning tunneling microscopy (STM) has the potential to enable simultaneous ångström-attosecond resolution. Here, we present our theoretical and experimental studies on the physical dynamics of attosecond STM. [mehr]

Correlation plays a central role in emergent phenomena. Examples include, among others, quantum ground states and collective excitations. Here, I will discuss what we can learn from time-domain views of correlation in two dimensional (2D) vdW materials. In the 2D vdW magnetic semiconductor, CrSBr, excitonic transition is found to strongly couple to magnetic order [1] and this allows the easy detection of low energy (GHz-THz) magnons by visible-NIR light [2].
