This is the simulation code for the paper Quantum simulations of the early universe. The files are:
integrator.py
: contains the RK4IP stepper based on reikna, and the corresponding integrator which performs full- and half-step propagation, comparing the results to estimate the convergence.wigner.py
: creates an initial state in Wigner representation and propagates it using the integrator.colors.xml
: a data file with values of main colors for plotting.mplhelpers.py
: backend settings formatplotlib
and color/style definitions for quality plots.mencoder.sh
: a batch file used to create movies out of plots withmencoder
.plot.py
: the main file, plots the graphs for the paper.
