Dear Alan,
I have been most interested to read your papers on quantum transport in
photosynthesis.
Graham Fleming and I were involved in writing the recent grand challenge
reports for DOE,
and my group has just published the first results of our snap-shot Xray
diffraction patterns
from molecules of photosystem 1 and photosystem 2, using the first X-ray
laser (the LCLS) at
Stanford. Our aim in these pump-probe studies is ultimately to make a
molecular movie of the
excited states of the photosynthetic reaction, hopefully at atomic
resolution.
This summer I'll be in Boston a fair bit, since my wife's family lives
there, and we have a house in
Newton. I'm writing to ask if there is a time we could meet to discuss the
possibility of imaging
the excitonic modes directly (in real space) using the technique described
in our recent Nature paper,
which I attach.
With best regards,
John.
PS. I'm teaching graduate condensed matter.
