Hello Everyone,
After getting feedback about when people can make it to group meeting,
we have officially decided to move group meeting this term to 3:00pm -
4:00pm (or 4:30pm depending on meeting length). This next part is
confusing: we will not start having group meetings at this new time
until 2/15. On 2/8 we will have group meeting at an anomalous time
(1:30-2:30). Tomorrow, we will have our last group meeting at the old
time of 2:30. All meetings will still be in the Division room. If any
of this is confusing, please see the calendar which I have recently
updated.
Tomorrow, Joey Goodknight will present his research on spectroscopy.
An abstract is provided below.
=======================
Experimentalists who practice electronic spectroscopy need a tool to
determine whether or not the excited states of two adjacent molecules
are coupled. More specifically, they need an unambiguous tool to show
that when the molecules are excited with light, that this coupling
begets a superposition between the two excited states (a coherence)
which lasts an appreciable amount of time. Having such a tool to
determine the existence of a long-lived electronic coherence would
allow for the resolution of certain controversies in quantum biology
regarding chlorophyll coherences and would be a highly useful tool to
guide future efforts towards developing artificial molecular
(excitonic) circuits. In this talk, I will discuss a possible
experimental methodology for being able to make this determination of
long-lived electronic coherences, where we know it theoretically works
and where it might not work and how we plan to go about testing it.
