In this talk, novel instrumentation techniques recently developed in Argonne National Laboratory to investigate quantum properties of individual nanoparticles, single molecules, and single atoms on surfaces as well as new quantum phenomena discovered by using these techniques will be presented. At the first part, the latest results of our synchrotron X-rays scanning tunneling microscope (SX-STM) will be shown. To date, synchrotron measurements vital for the characterization of materials at the nanoscale are performed by using conventional detectors.

I will give a brief introduction chiral symmetry and how broken symmetries are realized in a variety of assemblies. Among some interested assemblies are plasmonic superlattices that are able to break rotational and translational symmetries in a controlled manner. I will highlight some recent efforts into using plasmon hybridization to describe the plasmonic response of self-assembled superlattices.
