In this repository, you have access to the code used for the paper 'Topological multi-mode waveguide QED', by Carlos Vega, Diego Porras, and Alejandro González-Tudela. The repository contains the several files:
-
use-functions.py: Python script where the main functions used in the work are implemented.
-
Photonic_Bath_Features.ipynb: Jupyter notebook where we compute several quantites regarding the Harper-Hofstadter as a photonic bath, focusing on its eigenstates features at the lattice boundary.
-
Light_matter_interactions_Edge_HH_Lattice.ipynb: Jupyter notebook where we couple a quantum emitter to the edge of a Harper-Hofstadter lattice and simulate spontaneous emission dynamics and mode-selectivity with engineered non-local couplings.
