When: Tomorrow Wednesday Dec 14th 12-1 PM
Where: Cabot Division Room at Mallinckrodt
What: Joel is up for group meeting:
"*A witness for excitonic vs vibrational coherences *
The study of the excitonic network in the FMO complex is exciting because
apparently it supports long lived excitonic coherences. The direct
experimental evidence is from oscillations in 2D spectroscopy. However,
vibrational coherences also exhibit similar experimental signatures.
Whereas there is some body of evidence indicating that the quantum beats
are due to excitonic coherences (beating frequencies, computational
simulations), an experimental witness that can distinguish these two types
of quantum superpositions is required. In my talk, I'll show how ideal
broadband pump-probe experiments do the trick, and will discuss how this
can be approximated in nonideal situations".
