Exact and Truncated Dynamics in Nonequilibrium Field Theory
Gert Aarts, Gian Franco Bonini, Christof Wetterich
Nonperturbative dynamics of quantum fields out of equilibrium is often described by the time evolution of a hierarchy of correlation functions, using approximation methods such as…
On Thermalization in Classical Scalar Field Theory
Gert Aarts, Gian Franco Bonini, Christof Wetterich
Thermalization of classical fields is investigated in a ϕ^4 scalar field theory in 1+1 dimensions, discretized on a lattice. We numerically integrate the classical equations of mot…
Time evolution of correlation functions and thermalization
Gian Franco Bonini, Christof Wetterich
We investigate the time evolution of a classical ensemble of isolated periodic chains of O(N)-symmetric anharmonic oscillators. Our method is based on an exact evolution equation f…
The Semiclassical Description of Tunneling in Scattering with Multiple Degrees of Freedom
G. F. Bonini, A. G. Cohen, C. Rebbi +1
We describe a computational investigation of tunneling at finite energy in a weakly coupled quantum mechanical system with two degrees of freedom. We compare a full quantum mechani…
Tevatron Constraints on Topcolor-Assisted Technicolor
Yumian Su, Gian Franco Bonini, Kenneth Lane
We study the constraints on models of topcolor-assisted technicolor arising from measurements of high- jets and high-mass lepton pairs at the Tevatron collider. Existing data…
Transport Phenomena and Electroweak Baryogenesis in the Two-doublet Higgs Model
Gian Franco Bonini
We use transport equations to compute the evolution of the quark plasma at the electroweak phase transition in the two-doublet Higgs model, obtaining in a more rigorous and quantit…
