Finite density quantum field theories have evaded first principle Monte-Carlo
simulations due to the notorious sign-problem. The partition function of such
theories appears as the Fourier transform of the generalised density-of-states,
which is the probability distribution of the imaginary part of the action. With
the advent of Wang-Landau type simulation techniques and recent advances...

The combination of Dyson-Schwinger and Bethe-Salpeter equations allows, in principle, for an *ab-initio* continuum-QCD study of hadrons and their properties. Glueballs, mesons, baryons, etc. are all treated in a unified framework. Moreover it has the advantage that that it gives access to all momentum regimes and all quark masses, connecting the deep infrared to perturbative QCD and light- and...

In spite of a vast amount research over several decades, the behaviour of magnetic monopoles in quantum field theory is still poorly understood. Quantum field theory formulation of elementary magnetic monopoles is plagued by lack of manifest locality and Lorentz invariance, which makes calculations very cumbersome. Solitonic 't Hooft-Polyakov monopoles avoid this problem, but even in their...
