Code for time-evolving and finding steady states of permutation symmetric quantum mechanical problems
Hard Requirements:
python 3+
modern versions of scipy and numpy
Soft requirements:
qutip (for wigner functions)
matplotlib (for plotting)
tqdm (for progress bar in parallel construction of Liouvillian)
A basic example is given in run_Dicke.py
This sets up the problem studied in arXiv 1611.03342 of the dissipative Dicke model. It then solves for time evolution and the steady state.
To define a new model add to models.py. Example models are included: dissipative Dicke, pumped Dicke, three level system, laser and counter-laser.
