Violation of a Leggett-Garg inequality using ideal negative measurements in neutron interferometry
Elisabeth Kreuzgruber, Richard Wagner, Niels Geerits +2
We report on an experiment that demonstrates the violation of a Leggett-Garg inequality (LGI) with neutrons. LGIs have been proposed in order to assess how far the predictions of q…
Three-Path Quantum Cheshire Cat Observed in Neutron Interferometry
Armin Danner, Niels Geerits, Hartmut Lemmel +3
The paradoxical phenomenon of the quantum Cheshire Cat (qCC) refers to situations where different properties of a particle appear to be localised in different paths of an interfero…
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…
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…
Additive Manufactured and Topology Optimized Permanent Magnet Spin-Rotator for Neutron Interferometry Applications
Wenzel Kersten, Laurids Brandl, Richard Wagner +5
In neutron interferometric experiments using polarized neutrons coherent spin-rotation control is required. In this letter we present a new method for Larmor spin-rotation around a…
Comparison of mass renormalization schemes for simple model systems
E. V. Stefanovich, R. E. Wagner, Q. Su +1
We discuss an alternative method to mass renormalize a quantum field Hamiltonian based on a requirement that the vacuum and single-particle sectors are not self-scattering. We illu…
A study of local and non-local spatial densities in quantum field theory
R. E. Wagner, M. R. Ware, E. V. Stefanovich +2
We use a one-dimensional model system to compare the predictions of two different 'yardsticks' to compute the position of a particle from its quantum field theoretical state. Based…
