FFTArray: A Python Library for the Implementation of Discretized Multi-Dimensional Fourier Transforms
Stefan J. Seckmeyer, Christian Struckmann, Gabriel Müller +2
Partial differential equations describing the dynamics of physical systems rarely have closed-form solutions. Fourier spectral methods, which use Fast Fourier Transforms (FFTs) to…

Large, ultra-flat optical traps for uniform quantum gases
Kai Frye-Arndt, Matthew Glaysher, Marius Glaeser +7
Ultracold atomic gases with uniform density can be created by flat-bottom optical traps. These gases provide an ideal platform to study many-body physics in a system that allows fo…

Robust double Bragg diffraction via detuning control
Rui Li, V. J. MartÃnez-Lahuerta, S. Seckmeyer +2
We present a theoretical model and numerical optimization of double Bragg diffraction, a widely used technique in atom interferometry. We derive an effective two-level-system Hamil…
