This is a Python interface to AnyBubble, BubbleProfiler and CosmoTransitions for solving the bounce action.
>>> from bubbler import bubblers
>>> bubblers("0.1*((-x + 2)^4 - 14*(-x + 2)^2 + 24*(-x + 2))")
For plotting the profiles,
>>> from bubbler import profiles
>>> profiles("0.1*((-x + 2)^4 - 14*(-x + 2)^2 + 24*(-x + 2))")
This requires you to set paths to the codes
export PYTHONPATH=Absolute/Path/To/CosmoTransitions
export BUBBLEPROFILER=Absolute/Path/To/BubbleProfiler
export ANYBUBBLE=Absolute/Path/To/AnyBubble
The tests I shared before can be repeated by
python n_fields.py
python alpha_tests.py
NB I test against the develop branch of CosmoTransitions.
I added some convenience functions for investigating one-dimensional potentials
paramterised by E and alpha. E.g.,
>>> from bubbler import one_dim_profiles, one_dim_bubblers, one_dim_potential
>>> one_dim_potential(1., 0.6).plot()
>>> one_dim_bubblers(1., 0.6)
>>> one_dim_profiles(1., 0.6)
plots a potential, calculates the actions, and plots the field profiles for a
potential with E = 1. and alpha = 0.6.
