New Initial Conditions for Quantum Field Simulations after a Quench
M. Salle, J. Smit, J. C. Vink
We investigate a new way of using the quantum fluctuations in the vacuum as initial conditions for subsequent classical field dynamics. This method avoids problems with renormaliza…
Dynamics of Fermions and Inhomogeneous Bose Fields on a Real-Time Lattice
Gert Aarts, Jan Smit
The dynamics of the 1+1 abelian Higgs model with fermions is studied in the large N_f approximation, on a real-time lattice. The Bose fields obey effective classical equations of m…
Non-Equilibrium Dynamics with Fermions on a Lattice in Space and Time
Gert Aarts, Jan Smit
We consider the dynamics of the 1+1 dimensional abelian Higgs model with axially coupled fermions, in the large N_f limit, on a lattice in space and real-time. We allow for inhomog…
Numerical study of plasmon properties in the SU(2)-Higgs model
Jan Smit
We discuss an explorative computation of real time autocorrelation functions, in the classical approximation. The results for the `plasmon' frequencies and damping rates appear com…
Chern-Simons Diffusion Rate near the Electroweak Phase Transition for
Jan Smit, Wai Hung Tang
The rate of -violation in the standard model at finite temperature is closely related to the diffusion rate of Chern-Simons number. We compute this rate for $m_H \approx m_W…
Non-perturbative investigation of the fermion-Higgs sector of the standard model
Wolfgang Bock, Christoph Frick, Jan Smit +1
We present results for the renormalized quartic self-coupling $\lm_R$ and the renormalized Yukawa coupling in a fermion-Higgs model with two SU(2) doublets, indicating that w…
