Description

This dataset contains numerical data underlying figures describing the evolution of a scalar field and its quantum fluctuations inside an expanding bubble produced in a strongly supercooled first-order cosmological phase transition.

The deposited data cover four aspects of the calculation: the evolution of the effective equation-of-state parameter, the time evolution of the background scalar field and the renormalized root-mean-square field fluctuations, the energy spectrum of the produced fluctuations expressed as \(dE/d\log k\), and the energy budget of the bubble separated into background-field and fluctuation contributions.

The data include both the original time coordinates and, where used in the corresponding figures, dimensionless time variables rescaled by the temperature parameter \(T\). The energy-budget data contain several benchmark points corresponding to different choices of model parameters. The spectral data contain the momentum dependence of the fluctuation energy at several stages of the evolution and include the reliability cuts applied in the plotted results. Metadata files provide the relevant benchmark parameters, plotting conventions, units, and information on numerical processing.

The dataset is intended to enable reproduction of the published figures and independent analysis of the dynamics of the scalar background, particle production, equation of state, spectral energy distribution, and transfer of energy from the background field to fluctuations during the post-nucleation evolution of cosmological bubbles.

All the publication plots' data are uploaded in separate files. More detailed descriptions of the data can be found in the README files inside.
