AISim ‒ Simulations for light-pulse atom interferometry

AISim is a Python package for simulating light-pulse atom interferometers.

It uses dedicated objects to model the laser beams, the atomic ensemble and the detection system and store experimental parameters in a neat way. After you define these objects you can use built-in propagators to simulate internal and external degrees of freedom of cold atoms.

Installation

The latest tagged release can installed via pip with

pip install aisim

Alternatively, if you plan to make changes to the code, use

git clone https://github.com/bleykauf/aisim.git
cd aisim
pip install -e .

Usage

For basic usage and code reference, see the documentation.

Examples

Some examples are provided in the form of Jupyter notebooks:

• Effect of wavefront aberrations in atom interferometry
• Rabi oscillations with a Gaussian beam and thermal atoms
• Multiport atom interferometer
