33. The density of states approach for the simulation of finite density quantum field theories

Kurt Langfeld (Plymouth University)

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...

53. Hadron properties using Dyson-Schwinger and Bethe-Salpeter equations

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...

110. Quantum Field Theory of Magnetic Monopoles

Prof. Arttu Rajantie (Imperial College Sci., Tech. & Med. (GB))

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...
