Direct experimental test of commutation relation via weak value
Richard Wagner, Wenzel Kersten, Armin Danner +3
The canonical commutation relation is the hallmark of quantum theory and Heisenberg's uncertainty relation is a direct consequence of it. But despite its fundamental role in quantu…
Happy Birthday, Ultra-Cold Neutron!
Hartmut Abele, Tobias Jenke, Hartmut Lemmel
What is driving the accelerated expansion of the universe and do we have an alternative for Einstein's cosmological constant? What is dark matter made of? Do extra dimensions of sp…
Spin - Rotation Coupling Observed in Neutron Interferometry
Armin Danner, Bülent Demirel, Wenzel Kersten +4
Einstein's theory of general relativity and quantum theory form the two major pillars of modern physics. However, certain inertial properties of a particle's intrinsic spin are inc…
Multifold paths of neutrons in the three-beam interferometer detected by tiny energy-kick
Hermann Geppert-Kleinrath, Tobias Denkmayr, Stephan Sponar +3
A neutron optical experiment is presented to investigate the paths taken by neutrons in a three-beam interferometer. In various beam-paths of the interferometer, the energy of the…
