Structure and Coherence are not very important for light-harvesting efficiency

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.

Welcome! Welcome!

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.

Welcome, Kieron!

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.

 

Congratulations!

Congratulations to Tim Wiles, who passed his PhD viva yesterday, and becomes the first TMCS student to graduate from my group! Tim worked on the Unsöld correlation functional, which we’re now finding allows the construction of accurate DFT approximations with extraordinarily low self-interaction errors. More on that in an up-coming publication…

Congratulations also to former group member Mainak Sadhukhan, who just started a faculty position at the Indian Institute of Technology, Kanpur. Mainak worked in the group as a Royal Society Newton International Fellow, before moving on to work with Alexandre Tkatchenko in Luxembourg.

Welcome to new group members

We’re delighted to welcome Susannah Bourne-Worster and Zack Williams to the group!

Susannah just completed her DPhil with Prof Peter Hore at the University of Oxford, and was awarded a prestigious three-year fellowship by the Royal Commission for the Exhibition of 1851. She will be working on our project on understanding efficiency of energy transport in photosynthesis.

Zack completed year-one of the TMCS programme and has joined the group for his doctoral research. He will be picking up Tim’s project on correlation functionals using the Unsöld approximation.
