atomSmltr: a modular Python package to simulate laser cooling setups

Abstract

We introduce atomSmltr, a Python package for simulating laser cooling in complex magnetic field and laser beams geometries. The package features a modular design that enables users to easily construct experimental setups, including magnetic fields, laser beams and other environment components, and to perform a range of simulations within these configurations. We present the overall architecture of atomSmltr and illustrate its capabilities through a series of examples, including benchmarks against standard textbook cases in laser cooling.
