Event Details & Abstract: 

The table-top coherent extreme ultraviolet light source offered by high harmonic generation has opened up many new possibilities for studying nanostructured systems in unprecedented ways.Following an introduction to this generation process, I will discuss some of the ways we use this light source to follow heat flow and acoustic dynamics at the nanoscale – in the size regime where many of the traditional bulk models of behavior no longer apply. This is giving us new insight into the material and thermal transport behavior of materials at small scales. At the same time, because such nanostructured systems are ubiquitous in the technological world (for example, nano-electronics and integrated circuit components, hard drives, nano-medicine and more), understanding the new dynamics at this scale is imperative for the continued development and improvement of such systems.
