Achieving a near-ideal silicon crystal neutron interferometer using submicrometer fabrication techniques

Autor: M. G. Huber, B. Heacock, I. Taminiau, D. G. Cory, D. Sarenac, R. Valdillez, D. A. Pushin

Publikováno v: Physical Review Research, Vol 6, Iss 4, p 043079 (2024)

Perfect-crystal neutron interferometry, which is analogous to Mach-Zehnder interferometry, uses Bragg diffraction to form interfering neutron paths. The measured phase shifts can be used to probe many types of interactions whether it be nuclear, elec

Human psychophysical discrimination of spatially dependant Pancharatnam–Berry phases in optical spin-orbit states

Autor: D. Sarenac, A. E. Silva, C. Kapahi, D. G. Cory, B. Thompson, D. A. Pushin

Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-6 (2022)

Abstract We tested the ability of human observers to discriminate distinct profiles of spatially dependant geometric phases when directly viewing stationary structured light beams. Participants viewed polarization coupled orbital angular momentum (OA

Neutron sub-micrometre tomography from scattering data

Autor: B. Heacock, D. Sarenac, D. G. Cory, M. G. Huber, J. P. W. MacLean, H. Miao, H. Wen, D. A. Pushin

Publikováno v: IUCrJ, Vol 7, Iss 5, Pp 893-900 (2020)

Neutrons are valuable probes for various material samples across many areas of research. Neutron imaging typically has a spatial resolution of larger than 20 µm, whereas neutron scattering is sensitive to smaller features but does not provide a real

Angular alignment and fidelity of neutron phase-gratings for improved interferometer fringe visibility

Autor: B. Heacock, D. Sarenac, D. G. Cory, M. G. Huber, D. S. Hussey, C. Kapahi, H. Miao, H. Wen, D. A. Pushin

Publikováno v: AIP Advances, Vol 9, Iss 8, Pp 085115-085115-8 (2019)

The recent development of phase-grating moiré neutron interferometry promises a wide range of impactful experiments from dark-field imaging of material microstructure to precise measurements of fundamental constants. However, the contrast of 3% obta

Neutron Interferometry at the National Institute of Standards and Technology

Autor: D. A. Pushin, M. G. Huber, M. Arif, C. B. Shahi, J. Nsofini, C. J. Wood, D. Sarenac, D. G. Cory

Publikováno v: Advances in High Energy Physics, Vol 2015 (2015)

Neutron interferometry has proved to be a very precise technique for measuring the quantum mechanical phase of a neutron caused by a potential energy difference between two spatially separated neutron paths inside interferometer. The path length insi
