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…

A High-frequency, Low-power Resonant Radio-frequency Neutron Spin Flipper for High-resolution Spectroscopy
Sam McKay, Stephen J. Kuhn, Jiazhou Shen +7
We present a resonant-mode, transverse-field, radio-frequency (rf) neutron spin flipper design that uses high-temperature superconducting films to ensure sharp transitions between…

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…
