Orbital Angular Momentum Generation in Schwinger Scattering from Perfect Quartz
Niels Geerits, Anna-Sophie Berger, Hartmut Lemmel +4
Static electric fields have been suggested as a spin to orbital angular momentum converter in neutrons. Initial calculations showed that the field required to facilitate significan…

Measuring the Angular Momentum of a Neutron Using Earth's Rotation
Niels Geerits, Stephan Sponar, Kyle E. Steffen +6
A coupling between Earths rotation and orbital angular momentum (OAM), known as the Sagnac effect, is observed in entangled neutrons produced using a spin echo interferometer. Afte…
