Ask about how to determine if a simulation has dispersing domain walls.
- Currently using the domain wall ratio of the last frame.
- Domain wall ratio is variable though and it is not necessarily monotonic.
- i.e. could just be low right now but could increase later
- Maybe use the average of the last 30%? but how to determine how many values? The simulation could have just dispersed.
- Show off single and companion axion domain wall count plots.
- How do we determine domain wall dispersal for companion axion if there are two phases to worry about?
- Want complete dispersal? i.e. tag each phase has having dispersed or not and then rank the parameters as being more dispersive
or not.
- Does it make sense to get the average domain wall ratio by iterating over many seeds and then taking the mean?
- Maybe for one seed it disperses but another it doesn't and so the mean is now skewed by the different behaviour.
- When the field is dispersed, it hovers around a single value, could maybe take the standard deviation of the field and then
threshold?
- Can't run this analysis on single axion and companion axion in a reasonable amount of time. Need to implement this in the C++
version probably. Could use multiprocessing to speed it up but it would take all of the CPU.
- Vary K for single axion.
- Smaller value of K for companion axion model to limit artifacts
Instead of a plot of domain wall ratio vs some parameter, plot the domain wall ratio vs time and have different plot lines
for each parameter. Each model/set of parameters would be a range to signify the variability of the seeds. The general workflow
is like this:
save all plot data
- get all minimum/maximum values at each time OR
- use percentiles
- then use fill_between to fill the region between the two values
- plot a sample trajectory to get an idea of a typical path
