Theoretical Physics, Complex Systems, High Performance Computing
David Lancaster has returned to Theoretical Physics after an interlude teaching Computer Science. He is working in lattice gauge theory on ramifications of the LLR approach pioneered in Plymouth. This approach uses an approximation to the density of states as a way of computing observables and can lead to faster exploration of configuration space than traditional simulations.
In the earlier part of his career, David spent postdocs in Rome, Kyoto and Oxford working on subjects ranging from instantons to disordered systems. While teaching Computer Science he worked on the statistical mechanics of various complex problems motivated by Theoretical Computer Science.
