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…
One knob to tune them all: Phase-controlled photon statistics and linewidth in partially pumped atomic ensembles
Oksana Chelpanova, Martino Stefanini, Dusan Sarenac +2
We study a minimal model of collective light emission from an incoherently driven ensemble of atoms where incoherent drive is applied to only a subset of the atoms and show that bo…
Quantum Information Approach to the Implementation of a Neutron Cavity
O. Nahman-Lévesque, D. Sarenac, D. G. Cory +2
Using the quantum information model of dynamical diffraction we consider a neutron cavity composed of two perfect crystal silicon blades capable of containing the neutron wavefunct…
Generalizing the Quantum Information Model for Dynamic Diffraction
O. Nahman-Lévesque, D. Sarenac, D. G. Cory +3
The development of novel neutron optics devices that rely on perfect crystals and nano-scale features are ushering a new generation of neutron science experiments, from fundamental…
Remote state preparation of single photon orbital angular momentum lattices
Andrew R. Cameron, Sandra W. L. Cheng, Sacha Schwarz +7
Optical beams with periodic lattice structures have broadened the study of structured waves. In the present work, we generate spin-orbit entangled photon states with a lattice stru…
Talbot Effect of orbital angular momentum lattices with single photons
Sacha Schwarz, Connor Kapahi, Ruoxuan Xu +8
The self-imaging, or Talbot Effect, that occurs with the propagation of periodically structured waves has enabled several unique applications in optical metrology, image processing…
Generation and detection of spin-orbit coupled neutron beams
D. Sarenac, C. Kapahi, W. C. Chen +6
Spin-orbit coupling of light has come to the fore in nano-optics and plasmonics, and is a key ingredient of topological photonics and chiral quantum optics. We demonstrate a basic…
Coherence Optimization in Neutron Interferometry through Defocussing
J. Nsofini, D. Sarenac, D. G. Cory +1
A zero-area four-blade perfect crystal neutron interferometer (NI) possess a decoherence-free subspace (DFS) for low-frequency mechanical vibrations and thus is easier to site. %ha…
Methods for preparation and detection of neutron spin-orbit states
D. Sarenac, J. Nsofini, I. Hincks +5
The generation and control of neutron orbital angular momentum (OAM) states and spin correlated OAM (spin-orbit) states provides a powerful probe of materials with unique penetrati…
Noise Refocusing in a Five-blade Neutron Interferometer
J. Nsofini, D. Sarenac, K. Ghofrani +4
We provide a quantum information description of a proposed five-blade neutron interferometer geometry and show that it is robust against low frequency mechanical vibrations and dep…
Quantum Information Approach to Dynamical Diffraction Theory
J. Nsofini, K. Ghofrani, D. Sarenac +2
We present a simplified model for dynamical diffraction of particles through a periodic thick perfect crystal based on repeated application of a coherent beam splitting unitary at…
Spin-Orbit States of Neutron Wavepackets
Joachim Nsofini, Dusan Sarenac, Christopher J. Wood +5
We propose a method to prepare an entangled spin-orbit state between the spin and the orbital angular momenta of a neutron wavepacket. This spin-orbit state is created by passing n…
