In our new paper, recently published in J. Phys. Chem. Lett., we use a detailed Lindblad master equation to model exciton dynamics in the light-harvesting antenna of purple bacteria, as well as a series of hypothetical antenna systems with randomly generated structures.
Astonishingly, it appears the beautiful, symmetric structures of natural antenna are not necessary to achieve highly efficient exciton transport.
We are very excited to welcome the new additions to our group. From the left Dr. James Womack, who has returned after a postdoc with the Skylaris group in Southampton. Ollie who completed his MChem undergraduate degree with us earlier this year, Jillisa and Harry who are both part of the TMCS CDT.
In collaboration with Alec Wodtke (Max Planck Göttingen) and Tom Miller (Caltech), this work describes scattering experiments supported by simulations, and is featured on the cover of Science. The research reveals an ultrafast energy dissipation mechanism for atoms hitting an on-top site, in which up to 1–2 eV of kinetic energy is lost from the nascent C–H bond in as little as 10 fs, primarily through in-plane motion of the graphene carbon atoms.
We are very excited and honoured to welcome Prof Kieron Burke to Bristol for his sabbatical visit. Kieron is here as a Benjamin Meaker Visiting Professor, a scheme provided by the Institute for Advanced Studies. The plan is to work together on a range of areas at the interface between DFT and wavefunction methods. Kieron will be giving various talks and seminars during his visit (details to follow) and a short graduate-level course on exact properties of exchange and correlation functionals in DFT.
First it’s great to welcoming new postdoctoral research fellow Janus Eriksen to the group. Janus is self-funded through Independent Research Fund Denmark, and is joining the group after doing a Humboldt Fellowship with Jürgen Gauss in Mainz. Welcome to Bristol Janus!
Project entos goes from strength to strength, and as an outline and place holder for a fuller description of what we are doing, there is now a brief note on chemRxiv.
And finally, we had a great group hike in the Mendip Hills, south of Bristol. The weather was disturbingly good.
Callum (who organised it) had the honour of first reaching the “summit”. (I say “summit” because the altitude is about 300m or 1000 ft.)
Most of the group (Peter was taking the photo) in some ruin we found.
A warm welcome to Simon McKenzie, who is joining the group for a two-month sabbatical from his PhD with Prof Peter Gill at the Australian National University. Simon will be working on integral technology for the Unsöld project.
