Decoupling of a Neutron Interferometer from Temperature Gradients

December 16, 2016
Author(s)
Michael G. Huber, Muhammad D. Arif, P. Saggu, T. Mineeva, David Cory, Robert Haun, Ben Heacock, K Li, J. Nsofini, D. Sarenac, Chandra Shahi, V Skavysh, Mike Snow, S. Werner, A.R. Young, Dmitry Pushin
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 coherence requirements

Neutron Limit on the Strongly-Coupled Chameleon Field

March 11, 2016
Author(s)
Michael G. Huber, Muhammad D. Arif, David G. Cory, R. Haun, B. Heacock, Joachim Nsofini, Dimitry A. Pushin, P Saggu, C.B Shahi, William M. Snow, A.R. Young
The physical origin of the dark energy which 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 eld for dark energy coupling to

Survival analysis approach to account for non-exponential decay rate effects in lifetime experiments

January 13, 2016

Kevin J. Coakley, Maynard S. Dewey, Michael G. Huber, Hans P. Mumm, Alan Keith Thompson, Andrew T. Yue, C. R. Huffer, P. R. Huffman, C. M. O'Shaughnessy, K. W. Schelhammer, D. E. Marley
In experiments that measure the lifetime of trapped particles, in addition to loss mechanisms with exponential survival probability functions, particles can be lost by mechanisms with non-exponential survival probability functions. Failure to account for

Quantum correlations in a noisy neutron interferometer

September 15, 2014
Author(s)
Michael G. Huber, Muhammad D. Arif, Christopher Wood, D G. Cory, M. O. Abutaleb, Dimitry A. Pushin
We investigate quantum coherences in the presence of noise by entangling the spin and path degrees of freedom of the output neutron beam from a noisy three-blade perfect crystal neutron interferometer. We nd that in the presence of dephasing noise on the

Neutron Interferometric Measurement of the Scattering Length Difference Between the Triplet and Singlet States of N-3 He.

June 4, 2014
Author(s)
Michael G. Huber, Muhammad D. Arif, Wei-Chen N. Chen, Thomas R. Gentile, Daniel S. Hussey, T C. Black, Dimitry A. Pushin, F. E. Wiefeldt, C.B Shahi, L Yang
We report a new determination of the n-Helium-3 scattering length difference Δ b = (−5.411 ± 0.031 (statistical) ± 0.039 (systematic) ) fm between the triplet and singlet states using a neutron interferometer. This revises our previous result Δ b = (−5.610

Design of remnant magnetization FeCoV films as compact, heatless neutron spin rotators

April 5, 2013
Author(s)
Michael G. Huber, M. O. Abutaleb, Dimitry A. Pushin, Charles F. Majkrzak, Muhammad Arif, D G. Cory
We introduce a design of a neutron spin rotator for applications with space and temperature constraints. These passive devices employ remnant magnetization Fe- CoV thin films and can be tuned experimentally to achieve arbitrary rotation of an incident
