Finite temperature spectral functions in the $O(N)$ model

Show other versions (2)

We directly calculate spectral functions in the O(N) model at finite temperature within the framework of the functional renormalization group. Special emphasis is put on a fully numerical framework involving four-dimensional regulators preserving Euclidean O(4) and Minkowski Lorentz invariance, an i...
