      We find that annealing a previously chemically etched interferometer at 800 degrees C dramatically increased the interference fringe visibility from 23% to 90%. The Bragg plane misalignments were also measured before and ...

      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 ...
    • Neutron limit on the strongly-coupled chameleon field

      The physical origin of the dark energy that causes the accelerated expansion rate of the Universe is one of the major open questions of cosmology. One set of theories postulates the existence of a self-interacting scalar ...

      Nsofini, Joachim; Sarenac, Dusan; Ghofrani, Kamyar; Huber, Michael G.; Arif, Muhammad; Cory, David G.; Pushin, Dimitry A. (AIP Publishing, 2017-08-07)
      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 dephasing due to the dynamical phase. The ...

      The Precision Reactor Oscillation and Spectrum Experiment, PROSPECT, is designed to make both a precise measurement of the antineutrino spectrum from a highly-enriched uranium reactor and to probe eV-scale sterile neutrinos ...
    • Quantum-information approach to dynamical diffraction theory 

      Nsofini, Joachim; Ghofrani, Kamyar; Sarenac, Dusan; Cory, David G.; Pushin, Dimitry A. (American Physical Society, 2016-12-08)
      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 coarse-grained lattice sites. By demanding ...

      Nsofini, Joachim; Sarenac, Dusan; Wood, Christopher J.; Cory, David G.; Arif, Muhammad; Clark, Charles W.; Huber, Michael G.; Pushin, Dimitry A. (American Physical Society, 2016-07-13)
      We propose amethod to prepare an entangled spin-orbit state between the spin and the orbital angular momenta of a neutron wave packet. This spin-orbit state is created by passing neutrons through the center of a quadrupole ...
    • Structured Beams as Quantum Probes 

      Sarenac, Dusan (University of Waterloo, 2018-06-15)
      This thesis describes several projects under the common theme of generating and manipulating the spatial quantum phase structure of matter and electromagnetic waves. Experiments dealing with the following topics are ...
