    Frequently Asked Questions

    1. Why does QCD on a lattice work so well? Lattice simulations on 100 - 200 sites often yields interesting results.
    2. At what order would QED lose accuracy? Because of the Landau pole, the coupling blows up, perturbation theory must have limited applicability. Yet, no theory in physics has provided us with more accurate results, although corrections at comperatively high loop order have been included.
    3. When is a Wick rotation in QFT justified? Are there classes of theories for which it is not justified?
    4. What does the limit from QFT to QM look like? Furthermore, QM needs observables and an interpretation theory, which are both not prominent in the usage and development of QFT. Where have they gone?
    5. What do entangled states in QFT look like?
    6. How is it possible to reliably calculate error estimates in perturbation theory?
