Experimental test of symmetron-field based dark energy model using neutron interferometry
Andreas Dvorak, Kazuma Obigane, Hartmut Lemmel +2
We report phase shift measurements of neutron matter waves propagating in vacuum and low-pressure Argon gas, using a technique developed for neutron interferometric scattering leng…

Further search for magnetic-field-induced neutron disappearance in an ultracold neutron beam
Gaby Brenot, Benoit Clément, Hanno Filter-Pieler +7
We report the results of the second iteration of an experiment searching for neutron-hidden-neutron oscillations in a beam of ultracold neutrons, conducted at the PF2 facility of t…

Generalized Boundary Conditions for the qBounce Experiment
Eric J. Sung, Benjamin Koch, Tobias Jenke +2
Discrepancies between theory and recent qBounce data have prompted renewed scrutiny of how boundary conditions are implemented for ultracold neutrons bouncing above a mirror in Ear…
