Anomalous weak values in a generalized Mach-Zehnder interferometer extracted directly from intensity measurements

Ismaele V. Masiello, Hartmut Lemmel, Andreas Dvorak +2

Weak values provide a powerful framework for characterizing quantum systems. Their experimental extraction conventionally relies on weak conditioned von Neumann measurements, invol…

Reactor operation induced thermal effects on neutron flux measurements using He neutron detectors at a TRIGA Mk II research reactor

S. Dorer, C. Trunner, E. Jericha +5

A variation of the measured neutron flux using He detectors at a TRIGA Mk II nuclear research reactor during steady-state operation is reported in this article. The observed…

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…

Orbital Angular Momentum Generation in Schwinger Scattering from Perfect Quartz

Niels Geerits, Anna-Sophie Berger, Hartmut Lemmel +4

Static electric fields have been suggested as a spin to orbital angular momentum converter in neutrons. Initial calculations showed that the field required to facilitate significan…

Tight qubit uncertainty relations studied through weak values in neutron interferometry

Andreas Dvorak, Ismaele V. Masiello, Yuji Hasegawa +3

In its original formulation, Heisenberg's uncertainty principle describes a trade-off relation between the error of a quantum measurement and the thereby induced disturbance on the…

Covariant correlation-disturbance and its experimental realization with spin-1/2 particles

Ali Asadian, Florian Gams, Stephan Sponar

We formulate a precise tradeoff relation between correlation and disturbance for sequential -outcome quantum measurements in Hilbert spaces of arbitrary dimension. This relation…
