Abstract

We illustrate how geometric gauge forces and topological phase effects emerge in quantum systems without employing assumptions that rely on adiabaticity. We show how geometric magnetism may be harnessed to engineer novel quantum devices including a velocity sieve, a component in mass spectrometers, for neutral atoms or neutrons. We outline a possible experimental setup that demonstrates topological interferometry for neutral spin 1/2 systems.
