Abstract / Bemerkung
We investigate the dynamic critical behavior of a relativistic scalar field theory with Z2 symmetry by calculating spectral functions of the order parameter at zero and non-vanishing momenta from first-principles classical-statistical lattice simulations in real-time. We find that at temperatures above the critical point (T>Tc), the spectral functions are well described by relativistic quasi-particle peaks. Close to the transition temperature (T∼Tc), we observe strong infrared contributions building up. In the ordered phase at low temperatures (T
