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…
Spin-Energy Entanglement of a Time-Focused Neutron
J. C. Leiner, S. J. Kuhn, S. McKay +15
Intra-particle entanglement of individual particles such as neutrons could enable another class of scattering probes that are sensitive to entanglement in quantum systems and mater…
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…
Correcting Aberrations of a Transverse-Field Neutron Resonance Spin Echo Instrument
Stephen J. Kuhn, Sam McKay, Fankang Li +5
The neutron resonance spin echo (NRSE) technique has the potential to increase the Fourier time and energy resolution in neutron scattering by using radio-frequency (rf) neutron sp…
Spin-Textured Neutron Beams with Orbital Angular Momentum
Quan Le Thien, Sam McKay, Roger Pynn +1
We present a rigorous theoretical framework underpinning the technique of spin-echo modulated small-angle neutron scattering (SEMSANS), and show how the technique can be extended i…
Neutron State Entanglement with Overlapping Paths
S. J. Kuhn, S. McKay, J. Shen +12
The development of direct probes of entanglement is integral to the rapidly expanding field of complex quantum materials. Here we test the robustness of entangled neutrons as a qua…
