 ">Super-resolution microscopy of cold atoms in optical lattices</a>\nby Ch
 eng Chin (U Chicago) as part of Kadanoff seminars\n\n\nAbstract\nSuper-res
 olution microscopy has revolutionized the fields of chemistry and biology 
 by resolving features at the molecular level. With cold atoms\, such a sch
 eme can be applied to the length scale of atomic wavefunction and to perfo
 rm quantum control. Here we report super-resolution imaging based on nonli
 near response of optical pumping. With this technique the atomic density d
 istribution can be imaged with a half-width-at-half-maximum resolution of 
 16(2) nm and a localization precision below 0.5 nm. The short optical pump
 ing pulse of 1.4 us enables us to resolve fast atomic motion in the lattic
 e. A surprising application of our scheme is the emergence of moiré patte
 rns on the atomic cloud\, which we show to be immensely magnified images o
 f the atomic cloud.\n
