SUMMARY:Exploring the analogy between atoms and optical nanoresonators
    -- atomic metasurfaces\, super-scattering\, and super-radiant therm
 al emission\, R. G. Herb Condensed Matter Seminar\,  Zongfu Yu\, UW-Ma
 dison
DESCRIPTION:I will use a few examples to show that the exploration of 
 the analogy between atoms and optical nano-resonators could be quite i
 nteresting and useful. In the first example\, I will discuss how atoms
  might help to overcome the most daunting challenges in optical metasu
 rfaces\, which promise to revolutionize optical instruments by replaci
 ng delicate and expensive lenses with integrated flat components. Then
 \, I will discuss quantum antenna\, in an analogy to optical antenna. 
 I will show how to drastically enhance the optical cross section of at
 oms using topologically nontrivial optical media. Lastly\, I will disc
 uss the effect of super-radiance in thermal radiation\, which could pr
 ovide an interesting way to control thermal energy conversion.
