Non-perturbative Quantum Field Theory

The interest of our research group lies in the investigation of nonperturbative aspects of quantum field theories, mainly using numerical methods such as Monte Carlo methods. We are particularly interested in the properties of Quantum Chromodynamics (QCD) which is an integral part of the Standard Model (SM) of particle physics describing the fundamental forces between all known elementary particles. QCD defines the theory of the strong interactions between quarks and gluons governing the nuclear forces and the inner structure of hadrons, such as, for example, the proton, the neutron or the pion. QCD can be simulated as a quantum field theory on a four-dimensional hypercubic space-time lattice using high-performance supercomputers.
