Topological shaping of vortex neutron beams using forked phase gratings
S. McKay, S. R. Parnell, R. M. Dalgliesh +6
Beams of light or matter that carry well-defined states of orbital angular momentum (OAM) are promising probes of topological and textured condensed matter systems such as magnetic…
CANISIUS The Austrian Neutron Spin Echo Interferometer
Niels Geerits, Simon Hack, Lara Brukner +4
The broad band resonant spin echo interferometer, CANISIUS, is presented. CANISIUS is built in a versatile way, such that it can be operated in both a continuous broad band beam or…
Observation of a giant Goos-Hänchen shift for matter waves
S. McKay, V. O. de Haan, J. Leiner +8
The Goos-Hänchen (GH) shift describes a phenomenon in which a specularly-reflected beam is laterally translated along the reflecting surface such that the incident and reflected ra…
Neutron spin echo is a "quantum tale of two paths''
S. McKay, A. A. M. Irfan, Q. Le Thien +7
We describe an experiment that strongly supports a two-path interferometric model in which the spin-up and spin-down components of each neutron propagate coherently along spatially…
