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…
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…
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…
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…
