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 ... -
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 ... -
A sensitive search for dark energy through chameleon scalar fields using neutron interferometry
Snow, W. Michael; Arif, Muhammad; Heacock, Benjamin; Huber, Michael G.; Li, Ke; Pushin, Dimitry A.; Skavysh, Vladimir; Young, Albert R. (IOP Publishing, 2015-01-22)The physical origin of the dark energy, which is postulated to cause the accelerated expansion rate of the universe, is one of the major open questions of cosmology. A large subset of theories postulate the existence of a ...
