[Postgrad] Physics Society guest lecture - Dr Ben Hourahine on 11th March

Hi everyone,

Just a reminder of the Physics Society guest lecture:  Dr Ben Hourahine's talk will take place in TL423 at 5pm on Tuesday 11th March. This talk will be an interesting dive into the world of simulating semiconductor materials using DFT (density-functional theory), so please come along!

Abstract:

"A range problems in chemistry, physics and materials science need the solutions to the Schrödinger equation, which was postulated in 1925, but we still don't know how to do this exactly for more than 1 particle. Typically though, systems with many particles are of interest, so there has been nearly a century of attempts to approximately solve it, in a variety of different ways. One of the most famous is Density-functional Theory (DFT), which dates back to the 1960s and is almost the dominant method for modelling in materials science and lots of quantum chemistry. Unfortunately it's still too difficult to solve these equations for large or complex problems and for cases where long time scales are involved.

Here I'll talk about developing and using DFT-lite, specifically something called density-functional based tight binding, which is potentially as accurate as DFT but ~100-1000 times faster. I've been developing new methods in this area for 20+ years and will discuss some anecdotes from this experience."

I hope to see you all there!

Cheers,

Matt
