Classical density functional theory (DFT) is a microscopic approach for determining the average density distribution of a classical many-particle system in an arbitrary external potential. The approach is embedded in the framework of statistical mechanics and thermodynamics and is extremely powerful: Not only can one use it to accurately determine particle distributions, but one additionally gets thermodynamic quantities such as interfacial tensions, pressures and adsorptions. The applications of DFT have been numerous since its inception in the late 1970s, and in the last couple of decades the area has a renewed vigour thanks to the extension of the theory to cover dynamical non-equilibrium phenomena. This important extension is known as dynamical density functional theory (DDFT).
The goal of this workshop is to bring together mathematicians, physical scientists, materials scientists, and engineers working on developing and applying DFT and DDFT to discuss recent advances and to stimulate future work.
This workshop was postponed because of the 2020 pandemic. The rescheduled workshop will run online from Monday 3 to Thursday 6 May 2021. There is a workshop registration fee of 10.00 GBP for early career researchers and 30.00 GBP for all other participants. Registration has now closed.
The workshop will feature three plenary talks, giving overviews of (D)DFT from different perspectives, and laying the foundations for interdisciplinary conversations. There will also be a number of contributed talks and an opportunity for all participants to give a 'lightning' talk to highlight a particular aspect discussed at the workshop, or a topic for future discussion. There will be plenty of time for discussions and networking. Zoom will the online platform used to deliver the workshop and Sococo will be used for networking activities. There will also be a public lecture by Priya Subramanian (University of Oxford) on Tuesday 4 May on ‘Wielding the knowledge of what is not possible’.
