Coherence optimization in neutron interferometry through defocusing Open
A zero-area four-blade perfect crystal neutron interferometer (NI) possess a\ndecoherence-free subspace (DFS) for low-frequency mechanical vibrations and\nthus is easier to site. %has the potential to broaden the application of\ncrystal-ba…
Generation of a Lattice of Spin-Orbit Beams via Coherent Averaging Open
We describe a highly robust method, applicable to both electromagnetic and matter-wave beams, that can produce a beam consisting of a lattice of orbital angular momentum (OAM) states coupled to a two-level system. We also define efficient …
Quantum Information Enabled Neutron Interferometry Open
Neutron interferometry with its ability to encode and extract information provides a test \nbed for quantum mechanics and precise measurement of physical quantities of significant \nimportance in physics. However, this significant key inve…
Quantum-information approach to dynamical diffraction theory Open
We present a simplified model for dynamical diffraction of particles through\na periodic thick perfect crystal based on repeated application of a coherent\nbeam splitting unitary at coarse-grained lattice sites. By demanding\ntranslational…
Decoupling of a neutron interferometer from temperature gradients Open
Neutron interferometry enables precision measurements that are typically operated within elaborate, multi-layered facilities which provide substantial shielding from environmental noise. These facilities are necessary to maintain the coher…
Spin-orbit states of neutron wave packets Open
We propose a method to prepare an entangled spin-orbit state between the spin\nand the orbital angular momenta of a neutron wavepacket. This spin-orbit state\nis created by passing neutrons through the center of a quadrupole magnetic\nfiel…
Neutron limit on the strongly-coupled chameleon field Open
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 field for dark ene…
