Order Finding from Phase Dynamics in Topological Acoustics

This repository contains the analysis code and experimental phase data used for the manuscript:

Order Finding from Phase Dynamics in Topological Acoustics

Repository contents

• main.py — main analysis script.
• phases_1.mat — experimental phase data used by the script.
• results/ — generated figures and calibration parameters.
• requirements.txt — Python dependencies.

Requirements

The code requires Python 3.10 or newer.

Installation

Create a local virtual environment:

python -m venv .venv

Activate the environment.

On Linux/macOS with bash or zsh:

source .venv/bin/activate

On Linux/macOS with fish:

source .venv/bin/activate.fish

Then install the required Python packages:

python -m pip install --upgrade pip
python -m pip install -r requirements.txt

To confirm that the virtual environment is being used, run:

python -c "import sys; print(sys.executable)"

The printed path should point to .venv/bin/python inside this repository.

Reproducing the results

From the repository root, with the virtual environment activated, run:

python main.py

Alternatively, run the script explicitly with the virtual-environment Python:

.venv/bin/python main.py

The script reads phases_1.mat and writes the output files to the results/ directory. The expected outputs include:

• results/N55_a4_W8_Delta7.pdf
• results/N135_a4_W8_Delta10.pdf
• results/calibration_params_phi_12.txt
