SUMMARY:Quantum materials through the nano-lens: surprises beyond the 
 diffraction limit\, R. G. Herb Condensed Matter Seminar\, Alexander Mc
 Leod\, UMN
DESCRIPTION:Toolsets wielded by condensed matter researchers in the pa
 st century have expanded enormously into frontiers of the ultra-small 
 and ultra-fast\, today leveraging advancements like atomically precise
  crystal growth\, nano-scale device assembly\, and femtosecond spectro
 scopy with ultrafast photon pulses.  On the other hand\, despite breat
 htaking 20th century advancements in photon sources and detection tech
 nologies\, our capacity to resolve condensed matter by optical spectro
 scopies has remained largely arrested by the diffraction limit since i
 ts 19th century observation by Ernst Abbe.  However\, recent decades h
 ave seen the marriage of “conventional” optics with scanning probe
 s to circumvent the diffraction limit\, realizing a nanometer-resolved
  optical spectroscopy mediated fundamentally by electromagnetic near-f
 ields.  In this seminar\, I review and celebrate the breakthrough of t
 his technique into the temperature and spatial scales relevant to fund
 amental studies of quantum materials.  I showcase seminal investigatio
 ns of collective excitations in 2-dimensional media like graphene\, el
 ectronic phase competition in correlated electron solids including tra
 nsition metal oxides\, and on-demand control of optical properties in 
 strongly interacting materials.  I will share my perspectives for the 
 future of nano-spectroscopy of quantum materials\, a future that is si
 multaneously ultra-bright and ultra-small\, and fundamentally transfor
 mative for the study of complex matter at nanometer scales.
