Information Content of Spontaneous Symmetry Breaking
Marcelo Gleiser, Nikitas Stamatopoulos
We propose a measure of order in the context of nonequilibrium field theory and argue that this measure, which we call relative configurational entropy (RCE), may be used to quanti…
Three Dimensional Lattice Dispersion Relations for Finite Difference Methods in Scalar Field Simulations
Nikitas Stamatopoulos
We calculate the lattice dispersion relation for three dimensional simulations of scalar fields. We argue that the mode frequency of scalar fields on the lattice should not be trea…
Entropic Measure for Localized Energy Configurations: Kinks, Bounces, and Bubbles
Marcelo Gleiser, Nikitas Stamatopoulos
We construct a configurational entropy measure in functional space. We apply it to several nonlinear scalar field models featuring solutions with spatially-localized energy, includ…
Generation of Coherent Structures After Cosmic Inflation
Marcelo Gleiser, Noah Graham, Nikitas Stamatopoulos
We investigate the nonlinear dynamics of hybrid inflation models, which are characterized by two real scalar fields interacting quadratically. We start by solving numerically the c…
Emergence of Oscillons in an Expanding Background
E. Farhi, N. Graham, A. H. Guth +3
We consider a (1+1) dimensional scalar field theory that supports oscillons, which are localized, oscillatory, stable solutions to nonlinear equations of motion. We study this theo…
Unnatural Oscillon Lifetimes in an Expanding Background
N. Graham, N. Stamatopoulos
We consider a classical toy model of a massive scalar field in 1+1 dimensions with a constant exponential expansion rate of space. The nonlinear theory under consideration supports…
