SUMMARY:New Phenomena in Driven Quantum Systems - Shankari Rajagopal\, Uni
 versity of California\, Santa Barbara

DESCRIPTION:The isolated\, clean\, and tunable nature of ultracold gases m
 ake them a natural platform for controlled realization and study of Floque
 t physics and driven quantum systems. I will present recent results from t
 he Weld group discussing three experiments along these lines. First I will
  discuss an ultracold strontium experiment in which weak driving of a bich
 romatic lattice is used to probe novel excitation spectra in quasiperiodic
  systems. I will then talk about ultracold lithium in strongly modulated o
 ptical lattices\, including the mapping of a Floquet phase diagram and exp
 loration of a Floquet prethermal state. Finally\, I will present results f
 rom a new type of quantum simulator in which a driven Bose condensate of s
 trontium emulates ultrafast ionization dynamics in attosecond laser pulses
 \, counter-intuitively enabling the study of some of the fastest processes
  in atomic physics with some of the slowest.\n\n
