On the equivalence between the Boltzmann equation and classical field theory at large occupation numbers
A. H. Mueller, D. T. Son
We consider a system made up of exictations of a neutral scalar field, ϕ, having a λϕ^4 interaction term. Starting from an ensemble where the occupation number f is large, but λf i…
Classical Preheating and Decoherence
D. T. Son
We establish the equivalence between the quantum evolution of spatially homogeneous oscillations of a scalar field and that of an analogous classical system with certain random ini…
Singular Classical Solutions and Tree Multiparticle Cross Sections in Scalar Theories
F. L. Bezrukov, M. V. Libanov, D. T. Son +1
We consider the features of multiparticle tree cross sections in scalar theories in the framework of a semiclassical approach. These cross sections at large multiplicities have exp…
An Example of Semiclassical Instanton-Like Scattering: (1+1) Dimensional Sigma Model
V. A. Rubakov, D. T. Son, P. G. Tinyakov
A solution to the classical field equations in the massless (1+1)-dimensional O(3) sigma model is found, which describes a multi-particle instanton-like transition at high energy.…
