Non-classical neutron beams for fundamental and solid state research
The curious dual nature of the neutron, sometimes a particle, sometimes a wave, is wonderfully manifested in the various non-local interference and quantum contextuality effects observed in neutron interferome...

Test of quantum mechanics by neutron interferometry
Interferometry with massive elementary particles combines particle and wave features in a direct way. In this respect, neutrons are proper tools for testing quantum mechanics because they are massive, they cou...

Quantum contextuality induced by spin-path entanglement in single-neutrons
Since Einstein, Podolsky and Rosen suggested in the thirties and nowadays known as an EPR-paradox, non-local correlations between sufficiently separated subsystems have been extensively discussed. From a theor...

Precision measurement of the coherent neutron scattering length of 3He through neutron interferometry
Improved knowledge of the real part of the neutron scattering length of 3He is important for further development of nuclear few-body theory, as well as for a thorough understanding of neutron scattering off quant...

Neutron Spin Echo as a Quantum Interference System
Neutron spin echo systems use the superposition of two longitudinal wave fields with slightly different momenta produced either by the longitudinal Zeeman splitting in the case of dc spin echo systems or by a ...

Structural investigation of hybrid nanocomposites
Ultra small (USANS) and small angle neutron scattering (SANS) techniques were employed to study an elastomer styrene–butadiene, where two kinds of silica fillers have been added in different amounts. Small sil...

Off-diagonal geometric phase in polarized neutron interferometry
The concept of a Hamiltonian-independent geometric phase which depends only on the path of the evolution in parameter space is well established in a broad spectrum of physical phenomena. Recently it has been e...
