MOTorNOT v1.0.0

First tagged release of this fork. Builds on Robert Fasano's original semiclassical MOT scattering-force model and adds everything needed to simulate a full MOT → optical-dipole-trap transfer:

Added

  • CPU/GPU backend — every module dispatches through NumPy or CuPy transparently (get_array_module), so the same code runs on CPU or an NVIDIA GPU with no duplicated logic.
  • Optical dipole traps (dipole.py) — the AC-Stark potential for a focused Gaussian beam, a retro-reflected 1D lattice, or two crossed beams, with an exact analytic force (no finite differences).
  • Multi-level atomic dynamics (levels.py) — F=2 ↔ excited ↔ dark-F=1 rate equations with a repumper, including an exact (non-stiff) solve for the dark-state population.
  • Ensemble diagnostics (diagnostics.py) — temperature, velocity/position distributions and other cloud-level observables.
  • MOT → dipole recapture (recapture.py) — classical energy-criterion recapture accounting.
  • High-level API (api.py) and a backend-aware RK4 integrate() (integration.py) for driving a simulation end to end without touching the individual physics modules.
  • A physics-focused README with the equations behind each block.
