Welcome to TransitionListener’s documentation!¶
TransitionListener is a tool for simulating and analyzing cosmological first-order phase transitions and gravitational-wave signals.
About¶
TransitionListener is an open-source Python package designed to facilitate the analysis of extensions of the Standard Model of particle physics that feature first-order phase transitions in the early universe. It provides tools to compute the tunneling path of the scalar field(s), the thermodynamic parameters of the phase transition, and the resulting gravitational-wave spectrum. TransitionListener also includes functionalities for scanning parameter spaces and visualizing results.
Features¶
TransitionListener offers a comprehensive suite of features for simulating and analyzing cosmological first-order phase transitions and their associated gravitational-wave signals. Key features include:
Model-independent framework for analyzing first-order phase transitions
Phase tracing based on CosmoTransitions
Bubble nucleation rate calculation and determination of nucleation temperature
State-of-the-art computation of the bubble wall velocity
Self-consistent computation of the Hubble rate and the false vacuum fraction
Computation of the percolation and completion temperatures as well as the reheating temperature
Both the mean bubble separation and the inverse duration of the phase transition are calculated
Prediction of the gravitational-wave spectrum
Observability of the predicted gravitational-wave signal at current and future detectors
Many different scan options
Comprehensive plotting utilities for visualizing potentials, tunneling paths, bubble profiles, thermodynamic parameters, and gravitational-wave spectra
Modular and extensible codebase, allowing users to easily add new features or modify existing ones.
