Title: Quantum Chromodynamics on a lattice: supercomputers and a new mathematical trick

Abstract: Lattice QCD is the only systematic nonperturbative tool to do calculations in QCD. It has already been very successful at describing the empirically known particle spectrum, but important challenges lie ahead. I will describe two ways to meet these challenges. The first is the design of a special supercomputer optimized for lattice QCD. The second is a novel mathematical transformation (which originated in condensed matter physics) that can be used to reformulate lattice QCD, leading to improved fermionic algorithms.
