Phase Vortex Lattices in Neutron Interferometry
Niels Geerits, Hartmut Lemmel, Anna-Sophie Berger +1
A combination of aluminium prisms inserted into a nested loop interferometer is used to generate a neutron phase vortex lattice with significant extrinsic orbital angular momentum,…
Neutron interference from a split-crystal interferometer
Hartmut Lemmel, Michael Jentschel, Hartmut Abele +5
We report the first successful operation of a neutron interferometer having a separate beam recombining crystal. We achieved this result at the neutron interferometry setup S18 at…
Quantifying the presence of a neutron in the paths of an interferometer
Hartmut Lemmel, Niels Geerits, Armin Danner +3
It is commonly assumed that no accurate experimental information can be obtained on the path taken by a particle when quantum interference between the paths is observed. However, r…
