Visualizing Exotic Quantum States of Matter

Exotic quantum states are often studied via macroscopic measurements. These results rely on modeling to connect them to microscopic properties of electronic waves. This talk describes using spectroscopy imaging with a scanning tunneling microscope to probe and directly visualize electronic states on the atomic scale. I give examples of discovering electrons that behave as very massive particles because of their interactions or when the topology of their wave functions in solids gives them other characteristics very different than that of free electrons.
