Pendellösung length-scale neutron and X-ray interferometry
Owen Lailey, Alexandre Boutot, David G. Cory +12
Neutron and X-ray perfect-crystal interferometers (PCIs) are powerful platforms for studies of fundamental physics and phase-contrast imaging. Further enhancing several PCI capabil…
Probing Single-Particle Spatial Extent With Helical Neutron Wavefronts
D. Sarenac, O. Lailey, C. W. Clark +8
Distinguishing transverse coherence length from single-particle wavepacket extent is fundamentally challenging, as both manifest through spatial broadening of observed intensity pr…
Experimental Limit on Neutron Orbital Angular Momentum Detection Using Polarized 3He
D. Sarenac, O. Lailey, D. V. Garrad +11
A recent proposal suggested that neutron orbital angular momentum (OAM) states could be detected via spin-polarized absorption in polarized 3He, with predicted cross-section variat…
A generalized K-space coherent averaging method for engineering lattices of spin-orbit beams
Pinki Chahal, Naume Shentevski, Priyanka Vadnere +4
Spin-orbit beams, in which the orbital angular momentum degree of freedom is coupled to a two-level system such as polarization of light or spin in electrons and neutrons, have gai…
Topological Expansion of Boehm's Brushes via Structured Light
Dmitry A. Pushin, Iman Salehi, Amy Chow +10
We report a novel entoptic phenomenon in which the classical two-lobed Boehm's brushes are transformed into a multi-lobed structure by projecting spin-orbit coupled light onto the…
