Decoupling of a neutron interferometer from temperature gradients
Saggu, Parminder; Mineeva, Taisiya; Arif, Muhammad; Cory, David G.; Haun, Robert; Heacock, Benjamin; Huber, Michael G.; Li, Ke; Nsofini, Joachim; Sarenac, Dusan; Shahi, Chandra B.; Skavysh, Vladimir; Snow, W. Michael; Werner, Samuel A.; Young, Albert R.; Pushin, Dimitry A. (AIP Publishing, 2016-12-16)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 ... -
Holography with a neutron interferometer
Sarenac, Dusan; Huber, Michael G.; Heacock, Benjamin; Arif, Muhammad; Clark, Charles W.; Cory, David G.; Shahi, Chandra B.; Pushin, Dimitry A. (The Optical Society, 2016-10-03)We use a Mach-Zehnder interferometer to perform neutron holography of a spiral phase plate. The object beam passes through a spiral phase plate, acquiring the phase twist characteristic of orbital angular momentum states. ... -
Neutron interferometric measurement of the scattering length difference between the triplet and singlet states of n-He-3
Huber, Michael G.; Arif, Muhammad; Chen, Wangchun C.; Gentile, Thomas R.; Hussey, Daniel S.; Black, Timothy C.; Pushin, Dimitry A.; Shahi, Chandra B.; Wietfeldt, Fred E.; Yang, Liang (American Physical Society, 2014-12-15)We report a determination of the n-He-3 scattering length difference = b = = b = 1 -b = 0 = [-5.411 = 0.031 (statistical) = 0.039 (systematic)] fm between the triplet and singlet states using a neutron interferometer. This ... -
Neutron Interferometry at the National Institute of Standards and Technology
Pushin, Dimitry A.; Huber, Michael G.; Arif, Muhammad; Shahi, Chandra B.; Nsofini, Joachim; Wood, Christopher J.; Sarenac, Dusan; Cory, David G. (Hindawi, 2015)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
Li, Ke; Arif, Muhammad; Cory, David G.; Haun, Robert; Heacock, Benjamin; Huber, Michael G.; Nsofini, Joachim; Pushin, Dimitry A.; Saggu, Parminder; Sarenac, Dusan; Shahi, Chandra B.; Skavysh, Vladimir; Snow, W. Michael; Young, Albert R. (American Physical Society, 2016-03-11)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 ...
