DESCRIPTION:Abstract:\n\nSynchronization abounds in nature—why is it so har
 d to synchronize quantum systems? I will discuss this general question and
  its relationship to quantum coherence and exciton delocalization. I will 
 then report new experiments that show how a molecular exciton state can la
 unch two a superposition of two chemical reactions. Specifically\, we stud
 y femtosecond proton transfer in a symmetric molecule with two identical r
 eactant sites that are spatially apart. With the reaction launched from a 
 superposition of two local basis states\, we hypothesize that the motions 
 of the electrons and nuclei will ensue in lock-step as a superposition of 
 probability amplitudes until decoherence collapses the system to a product
 . We see evidence for this\, and conclude that this chemical system is a g
 ood test-bed to study the transition from quantum to classical.\n\n \n\nBi
 o:\n\nGreg Scholes is the William S. Tod Professor of Chemistry and Chair 
 of Department at Princeton University. This year he was selected as an ina
 ugural Ivy+ Provost Leadership Fellow with the goal of helping to advance 
 diversity and inclusion in the American professoriate. Originally from Mel
 bourne\, Australia\, he later undertook postdoctoral training at Imperial 
 College London and University of California Berkeley. He started his indep
 endent career at the University of Toronto (2000-2014) where he was the D.
 J. LeRoy Distinguished Professor. He was appointed Editor-in-Chief of the 
 Journal of Physical Chemistry Letters in 2019. Dr. Scholes was elected a F
 ellow of the Royal Society (London) in 2019 and a Fellow of the Royal Soci
 ety of Canada in 2009.\n
